d004e0b55c Cleanup resource flags
Converts GrResourceProvider::Flags and GrResourceCache::ScratchFlags
to "enum class" and fixes a case where we were accidentally using the
wrong type of flag. Makes sure to allocate GrSWMaskHelper proxies with
kNoPendingIO.

b2c4ea6219 Move Views into Sample and Viewer.
What is left of the SkView system is used only by samples or viewer.
As a result, move it out of the Skia source tree and re-organize so it
is a bit easier to understand and use more shared code.

Move samplecode/ClockFaceView.cpp to samplecode/SampleTextEffects.cpp,
sice that's what's actually in it.

Move SkAnimTimer.h to tools/timer, since it's actually shared between gm
and samples.

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.

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.

df04ce2949 ccpr: Draw curves in a single pass
Throws out the complicated MSAA curve corner shaders, and instead just
ramps coverage to zero at bloat vertices that fall outside the curve.

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

5183e649ef ccpr: Combine GS triangle hulls and edges into a single draw
Updates the geometry shader backend to match the vertex backend and draw
triangle rasters together with their their edges in a single draw call.
This gives a performance boost as well as cleaning up some API
awkwardness.

This is one step toward the final goal of drawing ccpr primitives in a single
pass.

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.
