b3105190a6 Store mipmap levels in deferred texture image
When creating the deferred texture image, detect if using medium / high
quality. If so, generate and store mipmaps in the deferred texture
image.

When creating a texture from that be sure to read it back out.

b4da01d8f7 Add prescale option to deferred params
Currently, Skia always uploads GPU textures at full resolution. This
change allows us to pass a pre-scale mip level to the
deferred texture image logic, which causes us to pre-scale the image
to the given mip level, and upload that mip level instead of the full
image.

eee3ced68f Disable tail calls inside Simple GM functions.
I haven't found any way to turn off the particular optimization (-foptimize-sibling-calls)
per-function, but I can control optimization settings coarsely:

   - on GCC, we can pick a particular -O level, so I've picked -O1 which does not
     enable -foptimize-sibling-calls
   - on Clang, we can only disable all optimization for a function
   - have no idea about MSVC

This should make sure the simple GM functions, e.g. all_bitmap_configs_GM(),
show up on stack traces when we crash.

ecbc12b1c1 Replace targetHasUnifiedMultisampling in GrPB constructor
Replaces targetHasUnifiedMultisampling with a simpler "useHWAA". Now
the code that creates a pipeline builder needs to decide on its own

builder to try and guess.

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

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

531237ef3a Tessellator: stop copying vertices into Polys and Monotones.
The vertices which are produced by stage 5 of the
tesselator are copied into the Polys and MonotonePolys it
produces. This is necessary because each vertex may have an
arbitrary valence, since it may participate in an arbitrary
number of Polys, so we can't use the vertex's prev/next
pointers to represent all the Monotones of which this
vertex may be a member.

However, each Edge can only be a member of two Polys (one
on each side of the edge). So by adding two prev/next
pointer pairs to each Edge, we can represent each Monotone
as a list of edges instead. Then we no longer need to copy
the vertices.

One wrinkle is that the ear-clipping stage (6) of the
tessellator does require prev/next pointers, in order to
remove vertices as their ears are clipped. So we convert
the edge list into a vertex list during Monotone::emit(),
using the prev/next pointers temporarily for that monotone.

This change improves performance by 7-20% on a non-caching
version of the tessellator, and reduces memory use.

Other notes:

1) Polys are initially constructed empty (no edges), but
with the top vertex, which is needed for splitting
Polys. Edges are added to Polys only after their bottom
vertex is seen.

2) MonotonePolys are always constructed with one edge, so
we always know their handedness (left/right).
MonotonePoly::addEdge() no longer detects when a monotone
is "done" (edge of opposite handedness); this is handled
by Poly::addEdge(), so MonotonePoly::addEdge() has no
return value.

33f6b3f6ee Manually generated sRGB mipmaps, with successively smaller draws.
Dirty GL-generated mipmaps whenever an sRGB texture is used with a new
value for TEXTURE_SRGB_DECODE. Add a new test rectangle to the gamma GM
that tests that textures are correctly converted to linear before
filtering when generating mipmaps.

Added a new unit test that alternates how a texture is interpreted (sRGB
or not), to verify that we rebuild mipmaps when needed, and that we get
the correct results out in both modes.

This test originally failed on four of our bots producing incorrect mips
in three different ways. I'm not real surprised, but it looks like
we can't rely on glGenerateMipmap to do the right thing, in conjunction
with TEXTURE_SRGB_DECODE.

Instead, actually create mip-chains using a series of draw calls.
(My first attempt used glBlitFramebuffer, and that still had bugs on
several bots). This approach appears to work correctly on any device
that fully supports sRGB.

Because the mipmap draws are fairly destructive to state, I had to
hoist them out of bindTexture. That means adding a second pass over
the texture accesses in the processor, at the very beginning of flush.

30e78c9737 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

- Add a test which decodes all scanlines using the new method
- Repurpose the Codec_stripes test to decode using the new method in

- In the method check(), add a parameter for whether the image supports

ba150cc283 always compute a cubic tangent
If the inflection of a cubic is also the cusp, the tangent
is degenerate at that t when computed directly. Rather than
giving up, subdivide the curve there and use the computed
control points to compute the tangent.

This strategy also removes the error paths where the tangent
formerly could not be computed.
