Join removed each merged anchor from the path's anchor list as it went,
which moved every anchor after it, so a long selected run in front of
many other anchors took time quadratic in the path's length. It also
looked up each anchor's selection in the selected-anchor set.
Join now marks the merged anchors and removes them in one pass at the
end, reading the selection from one flag per anchor. Each corner or
smooth conversion sees the same neighbors as before, so the resulting
anchors are unchanged. Anchor::smooth_between holds the smoothing that
SubPath::smooth_anchor applies.
Tests compare the new merge bit for bit with the old one on 30,000
generated paths, and count the anchors moved when 300,000 selected
anchors in front of 300,000 others merge: each of the others moves
once.
- When the faces that overlap form a cycle of depth orders, the order
broke the cycle only after drawing every face with nothing to wait
for, so a cap could be drawn before the walls and they painted over
it. A face drawn last now keeps its place: no face moves across it.
- A face with a corner at or past the eye, which the perspective
projection holds just in front of the eye, no longer gets a plane,
so its depth is not measured on a plane its drawing does not match.
- docs/three-d.md states the masked member rule in Groups as the
Fills and strokes section does, and docs/target-app-parity.md cites
the Inflate test by its name.
Clear, path.deleteAnchors, Cut, Copy and Cut Path scanned every selected
anchor or segment of a path once for each of its subpaths, so a path with
thousands of subpaths took time that grew with the square of their count.
The selection sets are ordered by subpath, so a new helper, subpath_refs,
reads one subpath's entries with a range lookup instead. The results are
unchanged.
With one selected interior anchor on each of 8,000 open subpaths of one
path, Clear took a median of 74 ms of thread CPU time before and 3 ms
after (release build, five runs each; the timings are noisy because the
CPU was shared and loaded).
Tests in delete_path_pieces.rs check exact surviving subpaths and their
order for anchor and segment selections across open and closed subpaths,
an untouched subpath, references to missing subpaths and indexes, one
Undo/Redo step and a second Clear, and Cut Path on several subpaths.
Without a plug-in store, plugin.install read the process grant once
for its later check and again for its approval. A grant another session
recorded between the two reads approved the module; when that session
revoked it before the install, the check saw the grant it first read
and the install recorded the revoked grant again. The approval now comes
from the first read.
plugin.install published the plug-in before it wrote the module and its
grant to the Plug-ins folder. A plugin.remove in another session in
between removed the plug-in, its file and its grant, and the install then
wrote both back, so the plug-in loaded with its grant at the next launch.
A session attaching the folder in between loaded the old version, which
kept running while the folder held the new one. plugin.remove, loads of
the stored plug-ins and loads of a plug-ins folder now wait until an
install has written the folder, and an install waits for them.

Assigning to a named child counts its list of the matching children, and
assigning through an empty XMLList counts the chain of targets it climbs,
before either changes the tree. copy(), toXMLString(), normalize(), the
`..` selector and the depth check on insertion hold the stack they keep
for each open level of the tree. Inserting an XMLList, and assigning one
to an item of an XMLList, hold their copy of the list's items.
copy() reads attributes in place, and toXMLString() reads attributes and
namespace declarations in place, instead of copying the lists. copy()
charges the declarations it copies before it copies them. Deleting by
name or assigning an attribute compacts the remaining links in place
instead of building a second list.
toXMLString() holds the set of prefixes a namespace lookup passes, and
picks a new nsN prefix in one pass over the declarations in scope
instead of rescanning them for each candidate.
The parser holds its open elements and their names, the text it gathers,
each tag's attribute values, the sets that check declarations and
attribute names, and its one copy of an element's namespaces, and it
charges the strings of the namespace declarations it makes. The
allowance it holds from the source's length covers the copy a value
takes as it becomes a string.
Comparing XML values, converting them to strings, assigning an XMLList
to an attribute, and reading a name, a qualifier, a namespace URI or
embedded text from a string built by joining strings flatten it with
flat_charged. An attribute name read from a string reserves its copy,
and an element name shares the string.

An <image> whose EXIF orientation or TIFF Orientation tag turns or flips
its pixels, linked or as a data URL, is turned before usvg reads it: the
pixels are stored as they are shown, the width and height swap, and the
box fits the turned image under preserveAspectRatio, as CSS
image-orientation: from-image describes. A turned CMYK JPEG or TIFF keeps
its inks as a CMYK TIFF, as does a CMYK TIFF that is not turned.
- Data URLs of type image/tiff, and untyped TIFF bytes, are read.
- TIFFs with extra channels, CCITT Group 3 TIFFs and planar CMYK TIFFs
are read as Open and Place read them.
- Converted images decode within the decode allowance, and a TIFF that
claims more strips or tiles than the decoder can count is refused
before any decoder opens it.
- exif_orientation moves to vectorcraft-doc so Open/Place and SVG import
share it.
Tests: crates/svg/tests/it/image_orientation.rs.
