AFAICT cc/output/gl_renderer.cc only calls SkImage:getTexture to determine the origin of the backing GrTexture. What do y'all think of this CL as a means of removing that call to getTexture?
One alternative would be to add a new entry point like:
bool SkImage::getBackendTextureDesc(GrBackendTextureDesc* desc) const;
which fills in the entire desc and returns whether the image is texture backed.

Our codec generator will now preserve any asked-for color space, and
convert the encoded data to that representation. Cacherator now
allows decoding an image to both legacy (nullptr color space), and
color-correct formats. In color-correct mode, we choose the best
decoded format, based on the original properties, and our backend's
capabilities. Preference is given to the native format, when it's
already texturable (sRGB 8888 or F16 linear). Otherwise, we prefer
linear F16, and fall back to sRGB when that's not an option.

This is a step towards using SkCodec in Chromium, where progressive
decoding is necessary.
Switch from using png_read_row (which expects all the data to be
available) to png_process_data, which uses callbacks when rows are
available.
Create a new API for SkCodec, which supports progressive decoding and
scanline decoding. Future changes will switch the other clients off of
startScanlineDecode and get/skip-Scanlines to the new API.
Remove SkCodec::kNone_ScanlineOrder, which was only used for interlaced
PNG images. In the new API, interlaced PNG fits kTopDown. Also remove
updateCurrScanline(), which was only used by the old implementation for
interlaced PNG.
DMSrcSink:
- In CodecSrc::kScanline_Mode, use the new method for scanline decoding
for the supported formats (just PNG and PNG-in-ICO for now).
fuzz.cpp:
- Remove reference to kNone_ScanlineOrder
SkCodec:
- Add new APIs:
- startIncrementalDecode
- incrementalDecode
- Remove kNone_SkScanlineOrder and updateCurrScanline()
- Set fDstInfo and fOptions in getPixels(). This may not be necessary
for all implementations, but it simplifies things for SkPngCodec.
SkPngCodec:
- Implement new APIs
- Switch from sk_read_fn/png_read_row etc to png_process_data
- Expand AutoCleanPng's role to decode the header and create the
SkPngCodec
- Make the interlaced PNG decoder report how many lines were
initialized during an incomplete decode
SkIcoCodec:
- Implement the new APIs; supported for PNG in ICO
SkSampledCodec:
- Call the new method for decoding scanlines, and fall back to the old
method if the new version is unimplemented
- Remove references to kNone_SkScanlineOrder
tests/CodecPartial:
- Add a test which decodes part of an image, then finishes the decode,
and compares it to the straightforward method
tests/CodecTest:
- Add a test which decodes all scanlines using the new method
- Repurpose the Codec_stripes test to decode using the new method in
sections rather than all at once
- In the method check(), add a parameter for whether the image supports
the new method of scanline decoding, and be explicit about whether an
image supports incomplete
- Test incomplete PNG decodes. We should have been doing it anyway for
non-interlaced (except for an image that is too small - one row), but
the new method supports interlaced incomplete as well
- Make test_invalid_parameters test the new method
- Add a test to ensure that it's safe to fall back to scanline decoding without
rewinding

Keep isOpaque as a convenience method -- many places really only need to

Currently, Skia always uploads GPU textures at full resolution. This
change allows us to pass a pre-scale mip level to the

# Not skipping CQ checks because original CL landed more than 1 days ago.
BUG=skia:4211

This is a step towards using SkCodec in Chromium, where progressive
decoding is necessary.
Switch from using png_read_row (which expects all the data to be
available) to png_process_data, which uses callbacks when rows are
available.
Create a new API for SkCodec, which supports progressive decoding and
scanline decoding. Future changes will switch the other clients off of
startScanlineDecode and get/skip-Scanlines to the new API.
Remove SkCodec::kNone_ScanlineOrder, which was only used for interlaced
PNG images. In the new API, interlaced PNG fits kTopDown. Also remove
updateCurrScanline(), which was only used by the old implementation for
interlaced PNG.
DMSrcSink:
- In CodecSrc::kScanline_Mode, use the new method for scanline decoding
for the supported formats (just PNG and PNG-in-ICO for now).
fuzz.cpp:
- Remove reference to kNone_ScanlineOrder
SkCodec:
- Add new APIs:
- startIncrementalDecode
- incrementalDecode
- Remove kNone_SkScanlineOrder and updateCurrScanline()
SkPngCodec:
- Implement new APIs
- Switch from sk_read_fn/png_read_row etc to png_process_data
- Expand AutoCleanPng's role to decode the header and create the
SkPngCodec
- Make the interlaced PNG decoder report how many lines were
initialized during an incomplete decode
- Make initializeSwizzler return a bool instead of an SkCodec::Result
(It only returned kSuccess or kInvalidInput anyway)
SkIcoCodec:
- Implement the new APIs; supported for PNG in ICO
SkSampledCodec:
- Call the new method for decoding scanlines, and fall back to the old
method if the new version is unimplemented
- Remove references to kNone_SkScanlineOrder
tests/CodecPartial:
- Add a test which decodes part of an image, then finishes the decode,
and compares it to the straightforward method
tests/CodecTest:
- Add a test which decodes all scanlines using the new method
- Repurpose the Codec_stripes test to decode using the new method in
sections rather than all at once
- In the method check(), add a parameter for whether the image supports
the new method of scanline decoding, and be explicit about whether an
image supports incomplete
- Test incomplete PNG decodes. We should have been doing it anyway for
non-interlaced (except for an image that is too small - one row), but
the new method supports interlaced incomplete as well
- Make test_invalid_parameters test the new method
- Add a test to ensure that it's safe to fall back to scanline decoding without
rewinding

The new version was generally faster than the old version (but not significantly so).
