Live Paint: a Cmd double-click or triple-click with the Bucket paints nothing

With Cmd (Ctrl) held, the Bucket's presses go to the selection tool Cmd
lends, but the double-click and triple-click that follow reached the
Bucket and painted. They now paint nothing, as with Alt.

Object › Live Paint › Make with a Live Paint group selected, and a Live Paint Bucket click on a selected path beside a selected Live Paint group, add the paths to that group the same way. Make, Merge and the Live Paint Bucket take paths, compound paths and groups of them; with type, an image or another object among the selection they report that it has to be converted to paths first and change nothing, as type and raster images can't go into a Live Paint group directly ([Create Live Paint groups](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/create-live-paint-groups.html)); before, such an object went among the group's hidden sources and vanished from the canvas. Evidence: `tests_build::live_paint_refuses_type_and_images_and_changes_nothing`.
   With the Live Paint Bucket selected, Alt-click on vector art samples its fill, stroke and stroke weight into the paint defaults ([Paint with the Live Paint Bucket tool](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/paint-with-the-live-paint-bucket-tool.html)). On a placed image it samples the image pixel as a solid fill with no stroke. Alt+Shift-click samples only the color under the pointer, including an intermediate gradient color or image pixels, into the active fill or stroke ([Default keyboard shortcuts](https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html)). Neither click paints or changes the selection or selected art, and the next Bucket click paints with the sampled paint. Evidence: `tests_build::live_paint_bucket_alt_sample_paints_next_face_without_changing_selection`.
   Double-clicking the Live Paint Bucket opens Live Paint Bucket Options ([Paint with the Live Paint Bucket tool](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/paint-with-the-live-paint-bucket-tool.html)): Paint Fills (on) and Paint Strokes (off) set whether a click paints faces, edges or both, Highlight turns the outline of the face or edge under the pointer on or off, and Color and Width set it (red and 4 px by default). Faces are outlined at the Width and edges at half of it, as the page says faces are highlighted with a thick line and edges with a thin line. With both on, a click paints the edge within 4 px of the pointer, else the face, and Shift switches to Paint Fills only; with one on, Shift switches to the other. The options last across tool switches and are saved with the preferences (`tool.setOption {tool: "livePaintBucket"}`).

-  Live Paint Bucket double-click and triple-click, as [the help page](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/paint-with-the-live-paint-bucket-tool.html) describes them: a double-click on a face fills it and the faces reached across edges that draw no stroke, and on an edge it paints the edges joined to it with the same stroke; a triple-click fills every face of the group with the face's fill, or paints every edge with the edge's stroke (`livePaint.fill` and `livePaint.strokeEdge` `{scope: "connected" | "samePaint", match?}`; `pointer_gesture` and `ui.pointer` take `tripleclick`). Each click paints as it arrives, as its own undo step, and the paint compared is the one the face or edge had before the first of its clicks that painted it; a first click that made the Live Paint group counts when the face it filled is the clicked face. With Space held for the view tools, a click, double-click or triple-click paints nothing and no face or edge is outlined.

   Live Paint Bucket Options has Cursor Swatch Preview, as the [help page](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/learn-painting-basics/paint-with-the-live-paint-bucket-tool.html) lists: with the Bucket selected, the active fill or stroke shows above the pointer between the color swatches before and after it in the Swatches panel, and the Left and Right arrow keys pick the swatch before or after it, as the page describes. The selected art keeps its paint. As VectorCraft's own rules, the option is on at first, the arrows step the stroke when the Stroke proxy is in front, they wrap around at the ends and still step with the preview off, a color that is no swatch shows alone until Right picks the first swatch or Left the last, and the arrows do nothing during a fill drag or with no color swatch. Evidence: `tests::build::{live_paint_bucket_arrow_keys_step_the_active_paint_through_the_swatches, live_paint_bucket_arrow_keys_handle_unmatched_paint_few_swatches_and_drags, live_paint_bucket_arrow_keys_pass_swatches_of_the_same_color_for_fill_and_stroke, swatch_arrow_keys_leave_modified_arrows_to_the_shortcuts}`.
   Live Paint Make preserves the front-most covering source's fill when compound paths share a curved boundary, and Expand keeps the face fills. Regression evidence: `planar::tests::coincident_curves_keep_their_source_faces` checks source order, winding, fill rules and nearby boundaries; `tests::build::live_paint_make_and_expand_keep_abutting_compound_colors` checks native compound paths, Make, Expand and Undo/Redo. This preserves VectorCraft's source-fill rule without changing arrangement precision.
   Live Paint Gap Options (Object › Live Paint › Gap Options…, `livePaint.gapOptions`): with Gap Detection on, paint stops at the gaps that run from a loose end of a path to the nearest path, up to Small (3 pt), Medium (6 pt), Large (12 pt) or a custom size; Close Gaps With Paths adds an unpainted path across each gap; Preview applies the options live and draws the gaps in the Gap Preview Color. The options are saved, copied and undone with the group, and Merge keeps the bottom group's options when its Gap Detection is on, or else turns Gap Detection on with Small when another merged group has it on. When Gap Detection is off in every merged group, it stays off.
