e23bffd65b379aeeb6bb614de81369c130623e92 02-Jun-2017 Brian Salomon <bsalomon@google.com> Remove support in GPU backend for distance vector field.

Also, remvoes SkNormalBevelSource as this was the last use case for the distance vector field.

33aa2c7b5c351c17a11ce2bf7d7cd70a3d86cecc 05-Apr-2017 Brian Osman <brianosman@google.com> Allow FPs to elevate default precision for the entire fragment program

Currently, GrConfigConversionEffect is able to round-trip on many
mobile GPUs because it uses highp for all intermediate variables
(including the texture fetch result). Separating the texture sample
into a different processor breaks that.

This is a blunt instrument, not to be used lightly.

This reverts commit dffe9827b18444d1426859d9035f9f0087201f44.

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.

This CL does two things. First it fixes a bug of ours where when using
a custom fbFetch variable (es 3.0 and higher), we sometimes overwrite
the out color and then attempt to use it as the dst color later. This is
fixed here by using an intermediate variable.

Secondly I've added a workaround to an andreno fbFetch where reading from
the outColor always returns the original dstColor even if we've overwritten
the value.

This update allows fragment processors to require a field of vectors to the nearest edge. This requirement propagates:

- from child FPs to their parent
- from parent FPs to the GrPaint
- from GrPaint through the PipelineBuilder into GrPipeline
- acessed from GrPipeline by GrGLSLProgramBuilder

GrGLSL generates a variable for the distance vector and passes it down to the GeometryProcessor->emitCode() method.

the GPU would always use the same sample pattern for render targets

that. This change improves the caching logic to handle mismatched
simple patterns with the same count, and adds a unit test that

87332103c605dc3e0f76c0d1250a76c4ff71fddc 26-Feb-2016 cdalton <cdalton@nvidia.com> Replace fWillReadFragmentPosition with a bitfield

Replaces fWillReadFragmentPosition on GrProcessor with a
"RequiredFeatures" bitfield. This will allow us to add additional
built-in features. Completely removes information about reading the
fragment position from GrPipeline and GrProcOptInfo.

c08f196648463d44eb85e17c5815dbf8f709a42a 12-Feb-2016 cdalton <cdalton@nvidia.com> Use noperspective interpolation for 2D draws

Adds a mechanism to notify GrGLSLVaryingHandler that a shader will not
emit geometry in perspective. This gives it a chance to use the
noperspective keyword if it is supported.

Updates the existing processors to notify the varying handler when
there is no perspective.

Begins using the noperspective keyword in GrGLGpu internal shaders.

Web scenes with observable benefit (Pixel C, gpu config):

tabl_nofolo.skp 4.62 -> 3.33 ms 28%
desk_tigersvg.skp 26.5 -> 24 ms 9%
desk_pokemonwiki.skp 16.1 -> 14.9 ms 7%
tabl_deviantart.skp 3.97 -> 3.7 ms 7%
desk_gws.skp 3.85 -> 3.65 ms 5%

Also adds new methods for creating varyings with flat interpolation.
