c571c001ce Revert of sRGB support in Ganesh. Several pieces: (patchset #12 id:220001 of https://codereview.chromium.org/1789663002/ ) 
Reason for revert:
We're getting sRGB non-8888 configs?

9e3f1bf4e5 sRGB support in Ganesh. Several pieces: 
sRGB support now also requires GL_EXT_texture_sRGB_decode, which allows
us to disable sRGB -> Linear conversion when reading textures. This gives
us an easy way to support "legacy" L32 mode. We disable decoding based on
the pixel config of the render target. Textures can override that behavior
(specifically for format-conversion draws where we want that behavior).

Added sBGRA pixel config, which is not-really-a-format. It's just sRGBA
internally, and the external format is BGR order, so TexImage calls will
swizzle correctly. This lets us interact with sRGB raster surfaces on BGR
platforms.

Devices without sRGB support behave like they always have: conversion from
color type and profile type ignores sRGB and always returns linear pixel
configs.

d77061067a Mv DRRect drawing code from GrDrawContext into SkGpuDevice 
This is a TODO left over from https://codereview.chromium.org/1731413002/ (Hide GrDrawTarget from GrOvalRenderer). It is desireable since the GrDrawContext doesn't, in general, manipulate GrFragmentProcessors.

f7b8b8affe Add wrapBackendTextureAsRenderTarget API 
Skia's GrTextureProvider currently exposes two APIs for wrapping backend
objects:
 * wrapBackendTexture - wraps a texture into a GrTexture. Depending on
   flags, this GrTexture can be converted to a GrRenderTarget. Skia
   manages the render target objects it may create to provide a render
   target for the texture. This allows Skia to create stencil buffers
   if needed and manager MSAA resolves.
 * wrapBackendRenderTarget - wraps a FBO into a GrRenderTarget. This
   object cannot be converted to a GrTexture. Skia does not manage
   the render target objects for such a GrRenderTarget, and as such
   cannot attach stencil buffers or perform MSAA resolves on the
   created GrRenderTarget.

Given these two options, wrapBackendTexture provides more versatility
and allows Skia more room for optimization. Chrome currently uses
wrapBackendTexture for this reason.

While these two functions cover most cases, they do not provide a way
for Skia to wrap a texture into a render target (and gain the MSAA and
stencil buffer management), without also creating a GrTexture. This is
problematic in cases where a texture can be bound to a render target,
but cannot be textured from, as is the case in Chrome's limited support
for GL_TEXTURE_RECTANGLE.

To address this, a new function is created:
 * wrapBackendTextureAsRenderTarget - wraps a texture into a
   GrRenderTarget. As with wrapBackendTexture, the created render
   target objects are fully managed by Skia. Unlike wrapBackendTexture
   no GrTexture is created, and the created object will never be
   textured from.

f15b07b75c Revert of Include glGetMultisamplefv API (patchset #1 id:1 of https://codereview.chromium.org/1720963002/ ) 
Reason for revert:
This is in the blamelist for Visualbench failures:

https://build.chromium.org/p/client.skia/builders/Perf-Ubuntu-GCC-ShuttleA-GPU-GTX660-x86_64-Release-VisualBench/builds/1035

and seems the most likely candidate for the failure, so I am tentatively reverting.

7023a00c35 Use unorm shorts for texture coordinates when rendering text. 
There are a couple of reasons for this:
- Vulkan does not guarantee conversions from integral vertex attributes
  to floating point shader variables
- This may be faster and more precise on some platforms, as it avoids
  the aforementioned conversion and changes a multiply by a very small
  value to a multiply by a medium-sized value.
