It is desirable that, when layer hoisting is disabled, the MPD and non-MPD timings be
roughly the same. Unfortunately, using a separate canvas for each tile (a requirement
for MPD) introduces its own discrepancy into the timing. Using a separate canvas for
each tile doesn't seem to make a difference for 8888 (see the non-MPD 8888 column below)
but slows down GPU rendering (see the non-MPD GPU column below). Since this is how
Chromium renders I propose switching to this regimen (even though it is "slowing down"
GPU rendering).

This CL makes the bounding box returned from SkMatrixImageFilter::computeFastBounds actually contain the final result pixels. This, in turn, fixes the first two rows of the filterfastbounds GM and the SVG web page cited in the bug.

Currently, the tile offset is added when drawing the picture. This might
have made a tiny bit of sense when the picture was always positioned at
origin, but with a picture cull rect offset things looks really strange.
For example, to specify a tile == the picture cull rect we have to pass
in [-cullrect.x, -cullrect.y, cullrect.width, cullrect.height]. Yikes.
(there's also a bug when not passing a tile, as we use a default tile
== cullrect but don't compensate for the above oddity)
This changes the semantics of the tile offset: it is now subtracted when
drawing the picture tile. As a consequence, one can pass in a tile equal
to the cull rect and get the expected behavior (same when not passing
a tile).
This will require a minor Blink change with the roll, as one client
works around the current behavior:

This new GM visualizes the fast bounds computed by various image-filter-based SkPaints. This is lead up to fixing some issues in fast bound computation.

PathOps relies on isConvex() only returning true for trivially
convex paths. The old logic also returns true if the paths that
contain NaNs and Infinities. Return kUnknown_Convexity instead
in those cases and in cases where the convexity logic computes
intermediaries that overflow.

This allows us to create distance field textures with better precision,
which may help text quality.

All of our font back-ends use the text size in some way other than
simple concatentation with the current matrix. The code here finds
the full device matrix and then decomposes it to extract the text
size.
FreeType, GDI, and DirectWrite use the text size as the pre-hint scale.
CoreText will not scale color emoji above the requested text size,
and certain features like 'trak' are performed on the text size.
