Some memory allocators have very coarse size buckets, so for example on
Android (jemalloc) an attempt to allocate 32 KiB + 1 byte will end up
allocating 40 KiB, wasting 8 KiB.
GrMemoryPool ctor takes two arguments that specify prealloc / block sizes,
and then inflates them to accommodate some bookkeeping structures. Since
most places create GrMemoryPools with pow2 numbers (which have buckets in
most allocators) the inflation causes allocator to select next size bucket,
wasting memory.
This CL makes GrMemoryPool to stop inflating sizes it was created with, and
allocate specified amounts exactly. Part of allocated memory is then used for
bookkeeping structures. Additionally, GrObjectMemoryPool template is provided,
which takes prealloc / block object counts (instead of sizes) and guarantees
that specified number of objects will fit in prealloc / block spaces.

For stages that have {r,g,b,a} and {dr,dg,db,da} versions, name the {r,g,b,a} one "foo" and the {dr,dg,db,da} on "foo_d". The {r,g,b,a} registers are the ones most commonly used and fastest, so they get short ordinary names, and the d-registers are less commonly used and sometimes slower, so they get a suffix.
Some stages naturally opearate on all 8 registers (the xfermodes, accumulate). These names for those look fine and aren't ambiguous.
Also, a bit more re-arrangement in _opts.h.

In the past, ANGLE always used GL_HALF_FLOAT. I filed a bug about that,
and they switched to HALF_FLOAT_OES. However, ES3 has direct support for
HALF_FLOAT, so we expect that as the format for read pixels.
The better solution would be to remember and return the value we get
back from IMPLEMENTATION_COLOR_READ_TYPE, but there are subtleties that
create additional bugs when we do that. In particular:
If trying to read Alpha8 from RGBA, the current sequence is:
1. readPixelsSupported asks for the format to use. getExternalFormat
switches out the format (assuming we're using GL_RED). This creates
a format/type pair that fails the ES3.2 rules (16.1.2), so we ask
the driver for the secondary format, which matches the one that we
expect (from our config table).
2. Then we *actually* do the readPixels, and here we just call
getReadPixelsFormat, which does the remapping, but skips the follow
up checks in readPixelsSupported. So we end up passing a format/type
pair that our code in readPixelsSupported thinks is illegal (and
which is neither the pair that our config table stores, *nor* the
pair returned by the implementation).
A straightforward solution of the original problem is to notice that
we had to ask the implementation (because the values are filled in),
so we should trust those and not the ones in the config table. But then
we miss out on the chance to overwrite the values for the alpha only
from RGBA case. Sigh.

Image shaders need to do some geometry work before sampling the image colors:
1) determine dst coordinates
2) map back to src coordinates
3) tiling
Feeding (x,y) through as (dr,dg) registers makes step 1) easy, perhaps trivial, while leaving (r,g,b,a) with their usual meanings, "the color", starting with the paint color.
This is easy to tweak into something like (x+0.5, y+0.5, 1) in (dr,dg,db) once this lands. Mostly I just want to get all the uninteresting boilerplate out of the way first.

This bug chromium:662780 exists after our original fix (https://codereview.chromium.org/2477393002/) because this path (added in unit test) is calling blitAntiRect rather than blitAntiH when the path is drifted across the boundary. (The quadratic edge drifts across the boundary after an update and sets a dX=0 line segment which triggers blitAntiRect.)
Note that I didn't assert for the dLeft = dRite = 0 case because the left/right there won't drift after the SkTMin/SkTMax in line 964/966.
Theoretically we can revert the relaxation in https://codereview.chromium.org/2477393002/ (that's only a relaxation for analytic AA, not supersampled AA). However, consider that the initial landing of analytic AA is so painful, I decide to revert that relaxation only after our successful landing...

Looking at SkSmallAlloc hasn't left me terribly impressed. I think we can replace it with something a lot simpler to work with.
That simpler thing's core would be something like SkFixedAlloc, which allocates objects out of a fixed sized buffer, and cleans them up when done.
If needed, we can wrap that with logic to try to allocate out of an SkFixedAlloc, falling back on mallc() when exhausted.

Reason for revert:
Crashing Mac Perf and Test bots.
This is a flaky but extremely likely crash. I've only seen one Mac Perf or Test bot that had this patch that didn't crash.
This should be easy to reproduce like this:
$ gn gen out --args=is_debug=false
$ ninja -C out dm
$ out/dm -m xfermodes3 --config gpu
This is crashing every time I run it on my laptop, and never when I revert this CL.
Building in release and running --config gpu probably don't matter.

Allow configs to be supported as FBO attachments for copies/readbacks without being "renderable" elsewhere in Ganesh.
The motivation for this is to add support for int textures as srcs but not as dsts (at least initially) but to still be able to read them back. This means we don't pay for a unneeded GPU copy when reading back a GrSurface that is a GrTexture and not a GrRenderTarget.

Updates the GrPipeline to have user stencil settings instead of actual

This change is a partial step. The ultimate goal is to attach the

flush, but for the sake of keeping this CL smaller, we create the
stencil settings right before use for now.

Add a new accessor to retrieve the repetition count.
Remove constants (and corresponding copyright) in SkCodecAnimation.
These may make sense for the calling code, but are not needed here.
kRepetitionCountInfinite corresponds to Blink's kAnimationLoopInfinite.
Move cLoopCountNotSeen to private. It is used to determine whether we
still need to parse. Add a new enum to the parse query - only parse
enough to determine the repetition count.
Unlike Chromium, SkGifCodec does not account for deleting the reader

While investigating skbug.com/5883 I noticed that we use the color
table for the current frame even while recursively decoding frames that
the current frame depends on.
This CL updates fCurrColorTable, fCurrColorTableIsReal and fSwizzler
before decoding prior frames, and then sets them back afterwards.
Move telling the client about the color table into prepareToDecode,
since the other callers do not need to do so. (That is only necessary
for decoding to index 8, which is unsupported for frames with
dependencies.)
Add a test that exposes the bug. colorTables.gif has a local color
table in its second frame that does not match the global table used by
the first frame.

Many places that construct one are explicitly specifying opaque white or
transparent black, which we can assume (based on the semantics of the
operation) should remain (0,0,0,0) or (1,1,1,1), so that's simple.
In other cases, we convert our source color to destination space.
One wrinkle is tht SkColorFilter now needs to know the destination color
space, due to SkModeColorFilter.

I'm not yet caching these in the blitter, and speed is essentially unchanged in the bench where I am now building and compiling the pipeline only once. This may not be able to stay a simple std::function after I figure out caching, but for now it's a nice fit.

Add an interface to decode frames beyond the first in SkCodec, and
add an implementation for SkGifCodec.
Add getFrameData to SkCodec. This method reads ahead in the stream
to return a vector containing meta data about each frame in the image.
This is not required in order to decode frames beyond the first, but
it allows a client to learn extra information:
- how long the frame should be displayed
- whether a frame should be blended with a prior frame, allowing the
client to provide the prior frame to speed up decoding
Add a new fields to SkCodec::Options:
- fFrameIndex
- fHasPriorFrame
The API is designed so that SkCodec never caches frames. If a
client wants a frame beyond the first, they specify the frame in
Options.fFrameIndex. If the client does not have the
frame's required frame (the frame that this frame must be blended on
top of) cached, they pass false for
Options.fHasPriorFrame. Unless the frame is
independent, the codec will then recursively decode all frames
necessary to decode fFrameIndex. If the client has the required frame
cached, they can put it in the dst they pass to the codec, and the
codec will only draw fFrameIndex onto it.
Replace SkGifCodec's scanline decoding support with progressive
decoding, and update the tests accordingly.
Implement new APIs in SkGifCodec. Instead of using gif_lib, use
GIFImageReader, imported from Chromium (along with its copyright
headers) with the following changes:
- SkGifCodec is now the client
- Replace blink types
- Combine GIFColorMap::buildTable and ::getTable into a method that
creates and returns an SkColorTable
- Input comes from an SkStream, instead of a SegmentReader. Add
SkStreamBuffer, which buffers the (potentially partial) stream in
order to decode progressively.
(FIXME: This requires copying data that previously was read directly
from the SegmentReader. Does this hurt performance? If so, can we
fix it?)
- Remove UMA code
- Instead of reporting screen width and height to the client, allow the
client to query for it
- Fail earlier if the first frame AND screen have size of zero
- Compute required previous frame when adding a new one
- Move GIFParseQuery from GIFImageDecoder to GIFImageReader
- Allow parsing up to a specific frame (to skip parsing the rest of the
stream if a client only wants the first frame)
- Compute whether the first frame has alpha and supports index 8, to
create the SkImageInfo. This happens before reporting that the size
has been decoded.
Add GIFImageDecoder::haveDecodedRow to SkGifCodec, imported from
Chromium (along with its copyright header), with the following changes:
- Add support for sampling
- Use the swizzler
- Keep track of the rows decoded
- Do *not* keep track of whether we've seen alpha
Remove SkCodec::kOutOfOrder_SkScanlineOrder, which was only used by GIF
scanline decoding.
Call onRewind even if there is no stream (SkGifCodec needs to clear its
decoded state so it will decode from the beginning).
Add a method to SkSwizzler to access the offset into the dst, taking
subsetting into account.
Add a GM that animates a GIF.
Add tests for the new APIs.
*** Behavior changes:
* Previously, we reported that an image with a subset frame and no transparent
index was opaque and used the background index (if present) to fill the
background. This is necessary in order to support index 8, but it does not
match viewers/browsers I have seen. Examples:
- Chromium and Gimp render the background transparent
- Firefox, Safari, Linux Image Viewer, Safari Preview clip to the frame (for
a single frame image)
This CL matches Chromium's behavior and renders the background transparent.
This allows us to have consistent behavior across products and simplifies
the code (relative to what we would have to do to continue the old behavior
on Android). It also means that we will no longer support index 8 for some
GIFs.
* Stop checking for GIFSTAMP - all GIFs should be either 89a or 87a.
This matches Chromium. I suspect that bugs would have been reported if valid
GIFs started with "GIFVER" instead of "GIF89a" or "GIF87a" (but did not decode
in Chromium).
*** Future work not included in this CL:
* Move some checks out of haveDecodedRow, since they are the same for the
entire frame e.g.
- intersecting the frameRect with the full image size
- whether there is a color table
* Change when we write transparent pixels
- In some cases, Chromium deemed this unnecessary, but I suspect it is slower
than the fallback case. There will continue to be cases where we should
*not* write them, but for e.g. the first pass where we have already
cleared to transparent (which we may also be able to skip) writing the
transparent pixels will not make anything incorrect.
* Report color type and alpha type per frame
- Depending on alpha values, disposal methods, frame rects, etc, subsequent
frames may have different properties than the first.
* Skip copies of the encoded data
- We copy the encoded data in case the stream is one that cannot be rewound,
so we can parse and then decode (possibly not immediately). For some input
streams, this is unnecessary.
- I was concerned this cause a performance regression, but on average the
new code is faster than the old for the images I tested [1].
- It may cause a performance regression for Chromium, though, where we can
always move back in the stream, so this should be addressed.

This test has nearly coincident lines that are missorted.
The underlying bug is caused when a pair of curves
are coincident when reduced to line segments, but the
end points aren't detected.
The error was generated by running nanobench over all svg
sample data with the distance field patch installed.

Matches our naming convention for all other types - factories that
return sk_sp (or any type that intelligently manages its own
lifetime) are named Make.
Previous factories are still around, assuming
SK_SUPPORT_LEGACY_COLOR_SPACE_FACTORIES is defined. Enable that
define for Android, etc.

Many old pathops-related fuzz failures have built up while
the codebase was under a state a flux. Now that the code
is stable, address these failures.
Most of the CL plumbs the debug global state to downstream
routines so that, if the data is not trusted (ala fuzzed)
the function can safely exit without asserting.
