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

9488833428 Refactored SkColorSpace and added in a Lab PCS GM
The refactoring breaks off A2B0 tag support into a separate
subclass of SkColorSpace_Base, while keeping the current
(besides CLUT) functionality in a XYZTRC subclass.

ICC profile loading is now aware of this and creates the A2B0
subclass when SkColorSpace::NewICC() is called on a profile
in need of the A2B0 functionality.

The LabPCSDemo GM loads a .icc profile containing a LAB PCS and
then runs a Lab->XYZ conversion on an image using it so we can
display it and test out the A2B0 SkColorSpace functionality,
sans a/b/m-curves, as well as the Lab->XYZ conversion code.

7c602de058 Removed makeLinearGamma() from the public API for SkColorSpace
It will now reside in SkColorSpace_Base. Future work for SkColorSpace
will cause this function to not be desirable or sensible to call on
all SkColorSpaces. Call sites were changed to make a kSRGBLinear_Named
instead of kSRGB_Named -> makeLinearGamma() (the majority of cases),
and if that was not possible, SkColorSpace_Base::makeLinearGamma()
was called instead.

eec8304714 Added kSRGBLinear_Named color space, along with tests
Gradients (and other shaders) are going to end up serializing this
particular color space very frequently, so we want a shorthand way of
writing it out. I think it's also helpful to have a clearer way of
creating it (vs. NewNamed(kSRGB_Named)->makeLinearGamma()).

f93d71122e SkFontData to use smart pointers.
The SkFontData type is not exposed externally, so any method which uses
it can be updated to use smart pointers without affecting external
users. Updating this first will make updating the public API much
easier.

This also updates SkStreamAsset* SkStream::NewFromFile(const char*) to
std::unique_ptr<SkStreamAsset> SkStream::MakeFromFile(const char*). It
appears that no one outside Skia is currently using SkStream::NewfromFile
so this is a good time to update it as well.

de68d6c461 Fix storage of gamut transform matrices in SkColorSpace
We were effectively storing the transpose, which made all of our
operations on individual colors, and our concatenation of matrices
awkward and backwards.

I'm planning to push this further into Ganesh, where I had incorrectly
adjusted to the previous layout, treating colors as row vectors in the
shaders.

ae6377c08e Make singleton SkColorSpaces thread safe
SkColorSpaces may be once-ptrs, so we can reuse common color spaces.
This means that they must be thread safe.  SkMatrix44 is not
thread safe because it maintains a mutable type mask.

This CL ensures that we precompute the type mask so we
can use const SkMatrix44's safely.

6fb2391b2c Make SkPngCodec decode progressively.
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

BUG=skia:4211

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

2c3eca38c9 Approximate common gamma tables as single values
This should improve performance of gamma conversion in
software (we can use vector math instead of table look
ups).

Additionally this allows us to quickly and easily
identify sRGB-like gammas.

On gpu, identifying sRGB gamma improves performance/memory,
because the hardware may support gamma conversion.

This will help us identify situations where gamma
conversion is not necessary.
Ex: sRGB input -> sRGB display
