641ac7daa8 Make result of GrOp::combineIfPossible be an enum.
This is to prepare for a third value that requests that ops be linked
together so that the first op may do the work for multiple linked ops
without actually merging the GrOp objects.

532b3f944a Remove clamping of kPlus with F16 configs
The most common use-case for F16 is to draw things that are explicitly
outside of [0,1]. We can't prevent out-of-range values in general, users
could just draw out-of-range content in src mode. We've decided that
it's best to avoid surprising behavior, and trust the user in these
situations.

493489054f Refactor GrPipeline dynamic state.
Remove scissor rect from GrPipeline.

Draws can specify "fixed dynamic state" which doesn't use the dynamism at
all or can specify dynamic state arrays with an entry per GrMesh.

When we state other than scissor rects this will allow the caller to
use a mix of truly dynamic and fixed dynamic state. So a caller that
only has dynamic scissor rects doesn't need to store its remaining
unvarying state in an array.

1471df99f0 Remove include of GrGLProgramBuilder.h from GrGLProgram.h and GrVkPipelineState.h
Make GrGLProgram and GrCkPipelineState cons. public and remove builder friendship.

Neither GrGLProgram nor GrVkPipelineState need to know their Desc so remove it.

Move the VK desc subclass defn. to GrVkPipelineStateBuilder since it needs it while
GrVkPipelineState does not.

Some IWYU improvements.

Move declaration of the built-in uniform struct to GrGLSLUniformHandler.h from GrGLSLProgramBuilder.h.

8738cf4c19 ccpr: Simplify triangle corners
Modifies triangle corner shaders to just approximate their coverage with
linear values that ramp to zero at bloat vertices outside the triangle.

For the vertex backend, since corners now have the same fragment shader
as the rest of the triangle, we fold them in with the other steps and
draw triangles in a single pass.

The geometry backend still draws triangles in two passes, as there is
not an apparent performance advantage in combining them.

Updates SampleCCPRGeometry to better visualize this new geometry by
clearing to black and drawing with SkBlendMode::kPlus.

2326177e34 CCPR: Don't use instanced draw calls with geometry shaders
It isn't necessary for the vertex shader to know all the points
because everything happens in the geometry shader. It's simpler to use
regular vertex arrays instead.

a3e9271ec4 CCPR: Eliminate texel buffers
Points cost 8 bytes and indices cost 4. If a point is accessed twice,
it's a wash whether we duplicate it or index. This change eliminates
texel buffers by duplicating points across instance arrays. This
reduces our dependence on extensions as well as getting rid of our
indirect memory access pattern in vertex shaders.

As a result of this change, memory usage by GPU buffers will only be a
fraction larger at worst, and slightly better at best.

7f578bf07b CCPR: Remove cubic insets and MSAA borders
Avoids the need for MSAA cubic borders by chopping up the cubic
geometry and crossing the inflections points and loop intersections
with lines and quadratic(s) instead. This allows us to render the
remaining cubic segments with simple hulls and analytic AA, giving
better image quality and performance.

b072bb6a5c CCPR: Process quadratic flat edges without soft msaa
The artifacts previously thought to require msaa can be handled by
(1) converting near-linear quadratics into lines, and (2) ensuring all
quadratic segments are monotonic with respect to the vector of their
closing edge [P2 -> P0].

No. 1 was already in effect.

No. 2 is implemented by this change.

Now we only fall back on soft msaa for the two corner pixels.

This change also does some generic housekeeping in the quadratic
processor.
