Add extended config specification form that can be used to run different
gpu backend with different APIs.
The configs can be specified with the form:
gpu(api=string,dit=bool,nvpr=bool,samples=int)
This replaces and removes the --gpuAPI flag.
All existing configs should still work.
Adds following documentation:
out/Debug/dm --help config
Flags:
--config: type: string default: 565 8888 gpu nonrendering
Options: 565 8888 debug gpu gpudebug gpudft gpunull msaa16 msaa4
nonrendering null nullgpu nvprmsaa16 nvprmsaa4 pdf pdf_poppler skp svg
xps or use extended form 'backend(option=value,...)'.
Extended form: 'backend(option=value,...)'
Possible backends and options:
gpu(api=string,dit=bool,nvpr=bool,samples=int) GPU backend
api type: string default: native.
Select graphics API to use with gpu backend.
Options:
native Use platform default OpenGL or OpenGL ES backend.
gl Use OpenGL.
gles Use OpenGL ES.
debug Use debug OpenGL.
null Use null OpenGL.
dit type: bool default: false.
Use device independent text.
nvpr type: bool default: false.
Use NV_path_rendering OpenGL and OpenGL ES extension.
samples type: int default: 0.
Use multisampling with N samples.
Predefined configs:
gpu = gpu()
msaa4 = gpu(samples=4)
msaa16 = gpu(samples=16)
nvprmsaa4 = gpu(nvpr=true,samples=4)
nvprmsaa16 = gpu(nvpr=true,samples=16)
gpudft = gpu(dit=true)
gpudebug = gpu(api=debug)
gpunull = gpu(api=null)
debug = gpu(api=debug)
nullgpu = gpu(api=null)

This CL may not really be necessary since it seems that the Android Ones we have fall back to mediump when highp isn't supported.
FYI, for bits-of-precision/precision we have:
Low Med High Precision-Used
A1 (Cherry One - Mali 400) 10 10 0 Med - conic looks bad
N5 (Adreno 330) 10 10 23 High - conic looks bad!!!
N6 (Adreno 420) 10 10 23 High - conic looks good
N7v2 (Adreno 320) 10 10 23 High - conic looks bad!!!
N9 (K1) 23 23 23 High - looks good
N10 (Mail-604) 10 10 23 High - looks good
I suspect derivative computation is broken on the Adreno 300s.

Replaces drawPathsFromRange with a more general drawPathBatch method.
While this still isn't perfect, it's a step in the right direction that
removes the need for path range draws to fit in a public API.

These sites don't necessarily need the full power of a GrRenderTarget object. This is a clean up for switching over to GrRenderTargetProxys.
Review URL: https://codereview.chromium.org/1486923004
This shouldn't really make any difference but allocating and holding on to a GrRenderTarget for each test target generates image differences for Mali GPUs. This CL allows an existing render target to be used for the test target.

Fixes rendering bugs and nondeterminism in gm.
Before, mixed samples stencil clip would try to infer whether the draw
wanted co-centered sample locations from within GrGLGpu, which caused
various errors. This change reworks it so the draw itself can request
the co-centered sample locations when it knows it will need them.
Also reduces framebuffer binds by moving the code that enables
GL_FRAMEBUFFER_PROGRAMMABLE_SAMPLE_LOCATIONS into flushRenderTarget.

Quits requiring EXT_raster_multisample and
NV_sample_mask_override_coverage for mixed samples support. This will
allow platforms without those latter extensions (i.e. Chrome) to still
use mixed samples for path rendering. Also moves the mixed samples cap
out of shader caps, since it no longer denotes shader functionality.
