A mesh read from a file can have any number of patches, and the view any zoom: a 150 x 150 mesh from a 3 MB file exported at 20x asked for about 23 million quads (2 GB), and the command's own cap of 50 rows and columns does not apply to a loaded one. One tessellation now makes at most 1,048,576 quads, the subdivision per patch giving way before that, and a mesh with more patches than that is malformed, like a point count that does not fit.
When the conjugate a ∘ self ∘ a⁻¹ overflows, conjugated now forms every
entry of the product as a sum of terms whose factors are split into a
mantissa and a power of two, and scales the whole product by one power of
two from its w row at the end. Scaling each partial product to a largest
entry of 1 could round an entry to 0 that the next factor would restore,
so a projection with entries far apart in size, such as a scale by
(1e160, 1e-160) seen through the same scale, was removed and the art drew
flat.
The move drag remembers the plane it places loose art on. Pressing 4
during the drag, or dragging on after it, previews and commits the move
on that plane instead of dropping it. A 1-3 key pressed before the drag
threshold also sets the plane the move uses.
The Bosnian catalog still carried the Color (,) and Gradient (.) rows, which no longer match the toolbar's tips. It now translates Color (, or Shift+,) and Gradient (. or Shift+.) like the other catalogs.
When the conjugate of a projection overflows, it is now formed one factor
at a time, and each partial product is divided by its largest entry
magnitude. Scaling the affine factors up front let the w row underflow to
0, so a scale by 2 seen through a move by 1e308 returned None and the
projection was removed, though its conjugate is finite.
perspective.move takes constrain: true instead of a plane-space
direction. For each object, the command snaps the move to the nearest
axis or 45-degree diagonal of that object's own plane, so a selection on
several planes keeps every object on a line of its plane. The tool sends
the raw pointer with the flag.
On a diagonal, Snap to Grid now moves along the diagonal by the nearer
per-axis correction, so that edge lands on its gridline.
When conjugating a projection overflows, the scaled-down result is now divided by the largest entry in its w row. A valid conjugate is no longer dropped by the determinant cutoff at the arbitrary scale, and every point of a kept projection passes the horizon test in apply instead of none.
perspective.move takes an optional constrain: [dx, dy], a plane-space
direction. For an in-plane move, Snap to Grid's correction is projected
onto that direction, so a move the Shift key constrains to a plane axis
or a 45-degree diagonal stays on that line when an object edge lies near
a gridline. The Perspective Selection tool sends the direction for
Shift moves and copies. Moves without the param behave as before.
The Color and Gradient tips now read "Color (, or Shift+,)" and
"Gradient (. or Shift+.)". The shortcuts follow the key positions, so on
layouts where Shift at those keys types another character the tips name
the keys to press. The 25 catalogs with these rows and the toolbar
accessibility test follow.
When moving type or a symbol instance in perspective makes the
conjugated projection overflow, Homography::conjugated now forms the
product from factors scaled to a largest entry of 1 and returns it at
that scale, which maps every point to the same place. When even the
scaled result is not invertible, the transform removes the projection
and the art is drawn flat, instead of keeping the old projection while
the flat art moves.
The key-position match for Shift+Comma and Shift+Period now applies only
when Shift is the only modifier. Cmd/Ctrl+Shift and Alt+Shift presses at
those keys keep their logical key, so the type-size shortcuts on German-like
layouts behave as before. The typing test also checks that no paint command
runs while text is edited.
Homography::apply checked that w is in front of the horizon but not the quotients, so a point with w just above 1e-9 and a large x or y, or a NaN w, mapped to an infinite or NaN point. apply now returns None unless the mapped point is finite. inverse, conjugated and affine_at return None when their result has an entry that is not finite.
The targets are in paint order, so the first selected object is not always the first target. The active row is now matched against the first selected object wherever it is among them.
With a fill row selected in the Appearance panel, Add New Fill now
inserts a copy of that row directly above it and selects the new fill.
Rows already above the selected one stay where they are. Before, the
new fill was always a copy of the topmost fill, added at the top.
The selected row belongs to the first selected object. In a mixed
selection, an object that shares that row gets the copy above its own
equal row; an object that does not share it gets a copy of its top
fill on top, as before. With a stroke row selected, or with `ids` or
`target: "contents"`, Add New Fill works as before.
The panel drops rows that were Cmd- or Shift-clicked together when the
active row changes outside the panel, so after Add New Fill (button,
menu or shortcut) only the new fill is selected.
transparency.makeOpacityMask with two or more layers below the mask
object (or a layer and objects of other layers) wrapped the layers
themselves in a new top-level group, so a layer ended up inside a
group. A layer among several masked items now stands for its art: the
masked group takes the layer's visible, unlocked objects, a hidden,
locked or template layer gives none, and the layers stay where they
are. One layer under a mask object, or one layer alone, is masked as
before.
Pattern tiles were drawn with the default render options, so an image
whose pixels cannot be decoded drew nothing inside a pattern fill even
when the render marks undecoded images, as the canvas does. Tiles now
follow the caller's mark_undecoded_images setting, and the tile cache
keys on it.
An opacity mask with such a pattern now treats the mark as part of the
mask, as it does for an undecodable image outside a pattern.
The renderer drew the root node of an opacity mask's art, of placed symbol
art, of an art brush piece, of an Image Trace source image and of a node
thumbnail without its own opacity mask. Make Opacity Mask uses the top
object as the mask art, so a mask made from an object that already had an
opacity mask ignored that inner mask. These roots now draw through the
same masked group as any other node, still drawn whatever their visibility
and bounds, and an incomplete inner mask still leaves out the outer object.
An art, scatter or pattern brush piece whose art carries a linked opacity
mask was bent along the path while the mask's art kept its place in the
brush's own coordinates, so the mask no longer covered the piece. The
mask's art now bends and has its strokes scaled with the object it
masks, on bent runs, on straight runs and where the brush narrows along
the path. A mask whose art cannot bend becomes an empty group. The
anchor budget for a brushed stroke counts the mask's art as well.
