Subject: [PATCH 1/5] SVG Interactivity: replies name JavaScript files outside
 the read roots by file name

With automation read roots in force, svgInteractivity.info and the files
reply of addFile and removeFile returned every linked JavaScript file as
stored, including paths outside the roots. They now name such a file by
its file name alone, as document.json does; a file inside the roots and
a URL are named as they are, and the document keeps every path.

removeFile also unlinks a file outside the roots by that file name. When
the name fits more than one linked file, it returns an error that names
no stored path and unlinks nothing. addFile still treats only the same
text as already linked.

In a frame a request drives, the JavaScript Files dialog lists such a
file by its file name while its selection keeps the file as linked, and
ui.inspect gives the selected file the same way. The person's frames
show full paths.

As in Illustrator the position isn't kept across launches. Not done: the bar's variants for other tools (only the selection tools and the Artboard tool show it).

Subject: [PATCH 2/5] Edit Colors: convert embedded images to indexed color

Edit > Edit Colors > Convert to Indexed Color... (edit.colors.toIndexed)
stores the embedded images in the selection as indexed-color PNGs: a
palette of at most 256 RGB colors, each pixel the index of one. The
dialog previews live and OK is one undo step.

- The palette is chosen as for a PNG-8 export (selective, perceptual,
  adaptive, web, gray, black and white), as evenly spaced levels of red,
  green and blue (uniform), or from the document's swatches. Dithering
  is diffusion, pattern, noise or none, with an amount.
- Pixels under half opacity become one transparent entry; the others
  become opaque in their own color. Linked images, colorized images and
  color glyph images keep their pixels.
- An image that is already an indexed PNG and would show the same pixels
  is left as it is, and no undo step is recorded when no image changes.
- An image of more than 134,217,728 pixels (33,554,432 in the web app)
  is refused, read from its header before decoding.
- With Select All, locked and hidden objects that hold an image that is
  not an indexed PNG yet are counted in notChanged, without converting
  them.
- The quantizer gains quantize_to, which maps pixels to a given palette.

The segmented wheel draws 24 hues by 5 saturations as solid patches, and its markers move freely as on the smooth wheel. The bars show one solid bar per recolored color in row order: a click selects a bar for the color sliders, and a drag moves its row without changing a color ([Advanced recolor options overview](https://helpx.adobe.com/illustrator/desktop/manage-colors/learn-color-basics/edit-colors-dialog-overview.html)). The dialog opens on the smooth wheel; `display` (`smooth`, `segmented`, `bars`) is the dialog field. `tests_recolor` covers switching, the dialog height, segmented dragging and Brightness, and bar selection, editing, reordering, scrolling, Preview, Cancel and OK.

A pasted code of three digits also replaces them, unless the paste holds only those digits and exactly three digits stay; those digits then edit the text in place. A press on another field commits the text as Tab and Enter do. As VectorCraft's own rule, a paste that is not a color leaves the field as it was. Tests: `a_hex_code_pasted_into_the_hex_field_replaces_its_digits` in `crates/ui-egui/src/dialogs/tests.rs`, `define_grid_takes_a_three_digit_color` in `crates/ui-egui/src/dialogs/tests_perspective.rs` and `a_paste_into_a_hex_field_replaces_or_edits_its_digits` in `crates/ui-egui/src/tests/numfields.rs`.
   - **Color Picker layout (#2008):** a centered draggable header, equal-width actions above aligned HSB/RGB/Hex and Lab/CMYK fields, compact field and slider, and warnings below the preview. No horizontal scrolling; narrow windows stack the sections with vertical scrolling. Tests in `dialogs/color_picker.rs` cover actual pointer/key input, typed values before OK/Enter, Cancel/Escape rollback, one Undo step, mode-size stability, warnings and layout at two UI scales. The screen sampler sits above the field and the upstream two-grid Tab order is retained. AccessKit regressions check the action names and each channel slider's displayed value, units and range. German and enlarged English UI renders were reviewed locally; no reference images are shipped. This is a layout improvement, with no change to scores or remaining-hour estimates.

Subject: [PATCH 3/5] Touch: canvas taps, presses and view navigation are
 ignored while a modal dialog is open

With Enable Touch Gestures on, a two-finger tap on the canvas undid and a
three-finger tap redid even while a modal dialog was open, and in the Touch
workspace a two-finger tap switched modes behind it. Fingers already down
when a dialog opened could still complete a tap when they lifted, during
the dialog or after it closed.

While a modal is open, from the frame it opens:
- no finger tap runs a command and no multi-finger gesture begins; the
  fingers already down are forgotten, so lifting them later runs nothing
- a primary press does not reach the tool, a middle-button press does not
  start a pan, and a double-click does nothing
- a long touch does not drop the canvas press
- a click in Presentation Mode does not step to the next artboard
- a pinch, wheel turn or trackpad rotation does not move the view, and the
  rest of a wheel turn made under the dialog is dropped after it closes;
  a new wheel turn after the dialog closes moves the view at once

   A two-finger rotation on a Mac trackpad turns the view about the pointer once it reaches 5° (Preferences › General › Trackpad Gesture to Rotate View, on by default).
   On a touch screen a second finger cancels the tool press the first finger began, in the frame it lands or later: the Pencil's stroke or a Selection move is rolled back with no undo entry, and a finger that lands while another is down presses nothing, so a pinch or two-finger pan only zooms and pans (#4198; canvas test `a_second_finger_cancels_the_tool_gesture_the_first_began`).
   In the Touch workspace a two-finger tap switches between the Selection tool and the drawing tool chosen last (the Pencil tool when none has been chosen yet) and undoes nothing; outside Touch it still undoes, and a three-finger tap still redoes ([the help page](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/touch-workspace-in-illustrator.html); `tool.toggleTouchMode`; canvas test `two_finger_tap_in_touch_switches_selection_and_drawing_modes`).
+  While a modal dialog is open, from the frame it opens, the canvas takes no new presses, double-clicks, finger taps, long touches, pinches or wheel turns, and a click in Presentation Mode does not step to the next artboard: a two-finger tap undoes nothing, a three-finger tap redoes nothing, a two-finger tap in the Touch workspace switches no mode, and fingers already down when the dialog opens make no tap when they lift, during the dialog or after it closes. This is VectorCraft's own rule (canvas tests `modal_blocks_two_and_three_finger_canvas_taps`, `opening_a_modal_discards_a_pending_canvas_tap`, `modal_blocks_presentation_tap_and_touch_navigation`, `modal_long_touch_does_not_cancel_canvas_press` and `modal_blocks_new_canvas_presses`).
   A tool press dropped by a second finger, a long touch or a canceled touch cancels the tool's drag as Escape does: the tool gets back the options it had when the press began (the Polygon tool's sides, set with ↑ and ↓) and they are not stored, a press held still opens no size dialog, a Selection or Artboard tool marquee selects nothing, and the Pen goes on drawing its path without the dropped anchor (canvas tests `a_canceled_touch_drops_the_drag_without_keeping_its_options` and `long_touch_drops_a_tool_press_without_committing_art`; engine tests in `tests::toolsettings`).
   The status bar navigator's field shows the active artboard's number and name, and its drop-down lists every artboard by number and name, as the Artboards panel does. Choosing an artboard in the list makes it the active artboard and fits it in the window (`view.goToArtboard`). The list opens on the active artboard's row and lays out only the rows in view and at most one more.

The Hindi catalog called a variable चर, परिवर्तनीय, वैरिएबल or
वेरिएबल from one row to the next: the Variables panel, Load and Save
Variable Library, Variable Options and the data-merge messages mixed
them, and so did variable widths, the font technology label and
environment variables. Every such row now says वेरिएबल (plural
वेरिएबल्स).

Close or Join, Join Point Text, Join the lines of each paragraph and
most of the path join messages said शामिल हों, which means joining a
group; the other join messages used जुड़ना, जॉइन or the English word.
They now say जोड़ें, as the Join command already did. The Discord rows
keep शामिल हों, and the stroke corner names and the Join tool keep
जॉइन.

hindi_rows_use_one_term_for_a_variable_and_for_joining_paths checks
both terms in every row. docs/localization-hi.md lists the terms, and
the Hindi row counts in it and in docs/localization-parity.md are
current (8,782 rows, 3,014 @msg).

Subject: [PATCH 5/5] Smooth tool: the drag shows the band the tool smooths

While the Smooth tool drags with a path selected that it can smooth, a
dashed outline shows the band its release smooths: every point within
the tool's radius (12 screen pixels) of the drag, round at both ends.
Alt smoothing with the Pencil, Paintbrush and Blob Brush shows the same
band. A selection with no path the tool can change shows none.

- The band is kept in squares eight radii wide, and each step of the
  drag adds its area only to the squares it reaches. A piece of a
  square's outline along a side is left out only where the square
  across holds band area.
- A drag segment too long for the squares (a jump drawn zoomed out and
  viewed zoomed in) keeps its band near each end in the squares and
  shows the rest as the two sides of its band. A step that cannot be
  added whole is added one segment at a time.
- A coarser grid of cells lists the squares and long segments, so a new
  one is checked only against those near it, and an outline is made
  again only where the band near it changed.
- After a zoom change mid-drag the band is outlined again a few hundred
  points per frame, and the work on long segments stops for the frame
  after a fixed budget. Tools report unfinished overlays with
  Tool::overlays_pending, and the canvas then draws again on the next
  frame, so the band covers the whole drag even while the pointer holds
  still.

   - **Drawing:** Pen, Curvature, anchor tools, Pencil, Paintbrush, Blob Brush, Smooth, Path Eraser, Join. Direction handles dragged with Direct Selection or the Anchor Point tool snap to smart guides, and Shift keeps them at 45° steps from their anchor. The Pen continues any open path from the end clicked, and while drawing, a click on an end of another open path joins the two into one (#776). The Curvature tool edits any selected path, whatever drew it, keeping its shape except where edited (#798): a click on a point makes it current and a drag moves it, re-curving only its two segments; double-click, or Alt-click on any point but an end of an open path, toggles it smooth or corner and Delete removes it; a click on a segment adds a point without changing the shape; with an end of an open path current, clicks go on from it and its other end closes it (`path.curvatureEdit`). An Alt-click on an end of a selected open path makes that end current without changing it, so the next click goes on from it, as [the help page](https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/draw-shapes/draw-shapes-with-the-curvature-tool.html) describes for continuing a path; an Alt-click that starts a new path places a corner point, as later Alt-clicks do. Every point a drawing tool places snaps to Smart Guides through one snapper (#506): the Pen's and Curvature tool's anchors, the Pencil's ends, the shape tools' start and dragged corner or radius (Rectangle, Rounded Rectangle, Ellipse, Polygon, Star, Line Segment, Arc, Spiral, the grids), the Type tool's click and frame, a new artboard's corners. A filled Pencil path keeps a stroke of None (#1804, part of #1679). While a Pencil or Paintbrush stroke is drawn back to within Close Paths When Ends Are Within of its start, the cursor shows the closing ring and a release there closes the path, as [Draw straight lines with the Pencil tool](https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/draw-shapes/draw-straight-lines-with-the-pencil-tool.html) describes for the Pencil. The [ and ] keys reach the Blob Brush, the Eraser and the Symbolism tools in the app (#1734, part of #1661).
     Blob Brush and Eraser Tool Options' Size is Fixed or Pressure with a Variation (#4590, #3961): with Pressure a pen stroke is Size − Variation wide where it presses lightest and Size + Variation where it presses hardest, and a mouse stroke keeps the Size.
     With the Blob Brush, Shift held during a drag keeps the stroke on the horizontal or vertical line through the press point, whichever is nearer to the pointer (90° steps from the Constrain Angle preference), and the points dragged since Shift went down move to the other line when the pointer crosses to it; the points dragged while Shift is up follow the pointer.
-    With the Blob Brush, Alt held before the press, or pressed before the drag has moved, switches to the Smooth tool, as the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists: the cursor shows the Smooth tool, the drag shows a thin line without the length label, Shift does not constrain it, and the release smooths the selected paths under the drag (`path.smoothRegion`) instead of painting; with nothing selected the release changes no path. A stroke that has moved keeps painting when Alt goes down.
-    Curvature point markers are circular, with no direction handles. While drawing, its own point feedback replaces generic selection markers; existing paths use the selection overlay, including partial selections and Hide Edges. Anchor Size applies, and Direct Selection and Pen retain their handles. The real egui-frame regressions in `crates/ui-egui/src/canvas.rs` verify marker positions, counts and unchanged documents (#1236, in part); the existing-path interpolation request remains open. The curve through the points (`curvature_spline` in `crates/tools/src/draw2.rs`) makes each stretch of three points follow the circle through them: a smooth point's handles lie along that circle's tangent, each `chord / (3 cos²(α/2))` long (α between handle and chord, capped at 90°), and the ends of an open path mirror their neighbour's tangent in their chord, so a J or a U curves evenly, a turn tighter than 30° comes to a point, and uneven spacing doesn't loop; the rubber band, a dragged or inserted point and `path.convertAnchor` to smooth use the same rule, while the Pencil's fitting keeps its own; `tests/draw2.rs` checks that the rubber band is the path the click makes (#1236, in part). The Smooth tool smooths only the stretch of path under the drag (#1547, fixes #1512). A path the Smooth tool changes stays selected whole, and the anchor points and segments selected on it with Direct Selection are deselected. Selected paths the drag does not change keep their selected anchors, and undo restores the earlier selection (`tests/draw2.rs`, `smoothing_a_path_drops_its_direct_selected_anchors`).

Selected paths the drag does not change keep their selected anchors, and undo restores the earlier selection (`tests/draw2.rs`, `smoothing_a_path_drops_its_direct_selected_anchors`). While the Smooth tool drags with a path selected that it can smooth, a dashed outline shows the band it smooths: everything within its radius of the drag (12 screen pixels, VectorCraft's own value), round at both ends; Alt smoothing with the Pencil, Paintbrush and Blob Brush shows the same band.
     While Alt is held during a Paintbrush stroke or before a press with no path selected that the Smooth tool can act on, the Paintbrush shows a closing cursor (a crosshair with a ring), and so does the Pencil with Alt key toggles to Smooth Tool off when Alt is pressed after the drag starts; releasing the mouse button with Alt still held closes the path. Before a Paintbrush press with such a path selected, Alt shows the Smooth cursor, and holding Alt at the press smooths that path with the Smooth tool's radius and Smooth Tool Options' Fidelity. A Pencil drag started with Shift or Alt held draws a straight line instead, which stays open.
     With Shift held at the press, the Pencil draws a straight line from the press point to the pointer at 45° steps from the Constrain Angle, as [Draw straight lines with the Pencil tool](https://helpx.adobe.com/illustrator/desktop/draw-shapes-and-paths/draw-shapes/draw-straight-lines-with-the-pencil-tool.html) describes; pressed on an end of a selected open path, the line continues the path from that end (part of #3799). With Option/Alt held at the press and Alt key toggles to Smooth Tool off, the Pencil draws a straight line at any angle, whose ends snap to Smart Guides, and it stays open when Alt is still held at the release; Shift and Alt together keep the 45° steps (#3799). While Shift or Alt is held before the press, the Pencil shows a straight-line cursor (a crosshair with a short line), and over an end of a selected open path, where the line continues the path, a path-continuation cursor (the same line leaving a small square), as the page describes.
   - **Shapes:** all shape tools (including Flare) and the line, arc, spiral and grid tools. Space held while dragging out a shape, line, arc, spiral or grid moves it at its current size. While a grid is dragged out, Up/Down change its rows (concentric dividers) and Left/Right its columns (radial dividers). A click with a grid tool asks for the size, the divider counts and the grid options (#1377, in part): a skew for each set of dividers, Use Outside Rectangle As Frame or Create Compound Path From Ellipses, and Fill Grid; they are parameters of `shape.rectangularGrid` and `shape.polarGrid`, stay as the tool's options and apply to drags too. A shape just drawn stays adjustable with its tool: its Live Shape widgets drag, a press on its centre point (Show Center) moves the selection with the Selection tool's move arrow, snapping and Alt copy, and a press in the rotate zone just outside a bounding-box corner turns it about the centre with the Selection tool's rotate cursor (#5477; tests `a_shape_tool_moves_the_selection_by_its_centre_point_and_turns_it_from_a_corner` and, through the engine, `shapetools.rs`). A drag on one of its eight bounding-box handles scales it as the Selection tool's handles do, with their cursors and snapping, instead of drawing a new shape from the handle. A shape tool takes a press as a handle's only on the drawn handle square (VectorCraft's own rule: 3 screen points from its centre along each axis at the default Anchor Size, a half point more or less per step; the Selection tool takes 5), so a press just beside a handle still draws (tests `a_shape_tool_scales_the_selection_by_its_bounding_box_handles`, `a_shape_tool_draws_from_a_press_just_beside_a_handle` and `a_shape_tool_scales_the_shape_just_drawn_by_its_bounding_box_handle`). The curve a skew percentage follows and the direction of the radial skew are our own (the public documentation gives neither), and the dialogs have no reference point locator. An ellipse's Pie Start and End Angle and Invert Pie (Transform and Properties panels' Ellipse Properties, `object.setLiveShape {pieStart, pieEnd, invertPie}`) cut it as a pie (#812). With the bounding box showing, the Selection tool shows a selected ellipse's two pie widgets just outside it; dragging one sets its angle in one undo step and double-clicking one makes the ellipse whole again. A live polygon's Polygon Properties there: side count, angle, corner type and radius, radius, side length and Make Sides Equal once an uneven scale has made its sides differ (`object.setLiveShape {sides, polygonAngle, polygonRadius, sideLength, makeSidesEqual}`, part of #812); a star is a plain path, as in Illustrator. The Flare Tool Options last as the tool's options: the next flare dragged out uses them, a click's dialog shows them and double-clicking the tool opens them (part of #812).
