c7d853343a Add disableStencil method to GrGLGpu
Most the calls to flushStencil were just trying to disable it. This
change cleans up that code so it can just call "disableStencil"
instead of having to muck with GrStencilSettings. It should also make
those calls slightly faster.

6ad9909fb7 Turn on -Wrange-loop-analysis.
-Wrange-loop-analysis triggers when we use a new-style for loop in a way that appears to unintentionally call a copy constructor on each non-trivial loop element instead of operating on them by reference.

82364bae16 Build for Android from Windows, work in progress.
Pretty vanilla stuff here, mostly just making the gcc-like toolchain Windows friendly.

I was having trouble getting rm -r {{output}} && $ar rcs {{output}} @$rspfile to work without deleting my ar.exe, so I chickened out the usual way by adding gn/ar.py.

I've also updated bin/droid to work with Git Bash on Windows.

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.

0057ac11fc Always use a color table with 256 colors
Speculative fix for skbug.com/5883

We are hitting an assert (which I have not been able to repro - still
need to get the skp that triggers it) because we are trying to read
beyond the end of the color table. We use 8-bit indices, so 256 should
be enough to prevent going beyond the end. There is only one case when
we use a smaller color table - when it is a dummy. Make the dummy full
size.

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.

aebfb45104 Move SkRasterPipeline further into SkOpts.
The portable code now becomes entirely focused on enum+ptr descriptions, leaving the concrete implementation of the pipeline to SkOpts::run_pipeline().

As implemented, the concrete implementation is basically the same, with a little more type safety.

Speed is essentially unchanged on my laptop, and that's having run_pipeline() rebuild its concrete state every call.  There's room for improvement there if we split this into a compile_pipeline() / run_pipeline() sort of thing, which is my next planned CL.

Prior to this CL, a kAnimated_Mode CodecSrc (which draws a strip of
all frames in an image) has the same name as a non-animated one. This
means that Gold compares the two. Someone triaging will see two very
different images (a strip versus a single image) and think one of them
is wrong.

With this change, the two will have different names so they will not
be compared with one another.

Two reasons for this:
(1) We care about the performance of this code, and Windows isn't
very good at inlining.  Let's make sure we isntruct the compiler
to inline.
(2) Since landing uses of this in Chrome, we're seeing flaky
LayoutTests that appear to be timing related.  I'm (very
optimistically) hoping that this will help.

026f223d86 Refactored SkColorSpace_A2B to allow arbitrary ordering of elements
This is essential for representing non-lutAtoBType A2B tags such as
lut16Type, lut8Type, mpet. Parsing of A2B0 tags was also moved ahead
of the TRC/XYZ-matrix parsing, as profiles examined with both tags
either had the TRC/XYZ tags as a fall-back or were incorrectly displayed
if only the TRC/XYZ tags were used.

This was submitted alone to reduce CL size. Tests that will use these changes will be introduced in the subsequent CLs that add on lut8/16Type A2B0 parsing. We already have lut16Type test images and these have been tested locally, but require additional code not submitted yet for lut16Type ICC profile parsing and A2B colorspace xforms.

3cc2d20509 Print what crashed DM on Android too.
This doesn't print a backtrace, but it's better than nothing.
By preserving the original signal handler and calling into that, we keep the Android system stack trace, visible in logcat, the "dump log" step on bots. 

Tested locally on Mac and Android by making an arbitrary GM segfault.

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.

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.

526972ecb5 Rename all color space factories from New* to Make*
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.
