dcfca431e3 Use GrContextFactories that produce a single GrContext in unit tests.
This is to alleviate problems due to the command buffer getting bent out of shape when the current
OpenGL context is switched out from under it (because we ran a test with a native GL context). This,
however is not a full solution. More changes will be required to ensure that after running each
command buffer or native test we bind the null context. This does allow us to take a step in that
direction without breaking anything too badly. Moreover, there is no real benefit to reusing a
GrContextFactory.

Modifies DEF_GPUTEST to take GrContextOptions rather than a factory to use. Tests were already using
their own factories anyway.

In tests that use GrContextFactory the factory instance is moved to the inner loop.

Modifies gpucts and skia_test to not use persistent GrContextFactories.

2890fbfe14 Make GrPipeline hold a GrRenderTargetProxy (instead of a GrRenderTarget)
In a future world where GrSurface no longer has an origin it will be
useful for the GrPipeline to be holding the GrRenderTargetProxy (which will
still have an origin).

46983b7dd8 Introduce dynamic pipeline state
Adds a DynamicState struct to GrPipeline that has a field for the
scissor rect. Eventually this should become the only way to specify a
scissor rectangle and may grow to contain more fields. Adds an array of
DynamicStates to GrGpuCommandBuffer::draw and implements support in GL
and Vulkan.

GrXPFactory::createXferProcessor now takes GrPipelineAnalysisColor and GrPipelineAnalysisCoverage rather than GrProcessorSet::FragmentProcessorAnalysis.

This will make it so ops do not have to retain the analysis or rerun it to create pipelines at flush time.

9f549358b3 Remove antialiasing control from GrPaint.
This adds an additional param (of new enum type GrAA) to draws that can antialias and a new enum GrAAType to indicate the AA technique (none, fragment shader computed coverage, msaa).

Some GMs change due to this:
1) In some places we weren't disabling MSAA when the draw was supposed to be unantialiased.
2) Some bounding rect draws that use GrFragmentProcessors were unnecessarily turning on antialiasing, by disabling it a very small number of pixel LSBs change.

c633abbb34 Remove GrStencilSettings from GrPipeline
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.

0d28e574ac Fix caching of sample locations
The original caching logic for sample locations wishfully assumed that
the GPU would always use the same sample pattern for render targets
that had the same number of samples. It turns out we can't rely on
that. This change improves the caching logic to handle mismatched
simple patterns with the same count, and adds a unit test that
emulates different sample patterns observed on real hardware.
