ce4d04ae8e Revert "Limit GL_TEXTURE_RECTANGLE filtering to bilinear."
This reverts commit 4d53c44aa6.

Reason for revert: Depends on https://skia-review.googlesource.com/c/4383/ which I need to revert.

Original change's description:
> Limit GL_TEXTURE_RECTANGLE filtering to bilinear.
> 
> Adds a clamp for GrTexture filtering that can be set by a subclass at construction. The clamping is performed by GrTextureParams. GrGLTexture limits filtering to bilinear for rectangle and external textures.
> 
> Also moves samplerType() to GrTexturePriv from GrTexture.

71d9d84d6c Use temporary FBO for GrGLGpu::onReadPixels.
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.

c633abbb34 Remove GrStencilSettings from GrPipeline
Updates the GrPipeline to have user stencil settings instead of actual
settings. This allows us to further defer creating and attaching a
stencil buffer.

This change is a partial step. The ultimate goal is to attach the
stencil buffer and create the stencil settings during render target
flush, but for the sake of keeping this CL smaller, we create the
stencil settings right before use for now.

e71b1a1496 Report repetition count in SkCodec
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
(which SkGifCodec does not do) or failed decodes.

Add a test.

fc49b403eb Use correct color table for prior GIF frames
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.

Removing these from the public API makes it easier to ensure users are

This also updates GrGpu::wrapBackendXXX and the

bd3fe475b8 Convert SkRasterPipeline loads and stores to indirect.
This allows us to change the underlying pointer without rebuilding the pipeline, e.g. when moving the blitter from scanline to scanline.

The extra overhead when not needed is measurable but small, <2%.  We can always add back direct stages later for cases where we know the context pointer will not change.

618d304eb3 GrConstColorProcessor uses 4f colors in the destination space
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.

e9f74b89c0 SkRasterPipeline::compile().
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.

19b91531e9 Add support for multiple frames in SkCodec
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.
