Reworks GrGLGpu to track GL buffer state based on the unique
GrGpuResource ID. This eliminates the need to notify the gpu object
whenever a buffer is deleted.
This change also allows us to remove the type specifier from GrBuffer.
At this point a buffer is just a chunk of memory, and the type
given at creation time is just a suggestion to the GL backend about
which target to bind to for updates.

Also added SkSurfaceProps to SkSpecialImage, so that Image -> Surface conversion can preserve the desired behavior during filtering.
Many small changes, including a bunch of comments about places where we may be losing information right now. My approach was to ensure that if anything fails, it will always fall back to "legacy" mode - gamma-correctness is opt-in, so I'll just have to feed things through as missing cases are exposed.

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.

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.

Remove refcounting from SkGLContext.
SkGLContext is expected to behave like GrContextFactory would own
it, as implied by the GrContextFactory function.
If it is refcounted, this does not hold.
Also other use sites, such as in SkOSWindow_win (command buffer gl
object), confirm the behavior. The object is explicitly owned and
destroyed, not shared.
Also fixes potential crashes from using GL context of an abandoned
context.
Also fixes potential crashes in DM/nanobench, if the GrContext lives
longer than GLContext through internal refing of GrContext.
Moves the non-trivial implementations from GrContextFactory.h to
.cpp, just for consistency sake.
Changes pathops_unittest.gyp. The pathops_unittest uses
GrContextFactory, but did not link to its implementation. The reason
they worked was that the implementation used (constructors, destructors)
happened to be in the .h file.
This works towards being able to use command buffer and NVPR from
the SampleApp.

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.

This allows internal Gr texture creation code to succeed for extraneous textures while running the bleed GM. This means we can turn on the shader variants.

Logically this CL:
Moves the PathRendererChain from GrContext to GrDrawManager
- this was needed to untangled the Path-Chain/Renderer header mess
- this entailed adding getDrawingMgr so the CMM could access the PathRenderingChain
- this also entailed re-adding freeGpuResources to the GrDrawingMgr
Moves the CanDrawArgs struct up stack
Removes the GrPipelineBuilder from the CanDrawArgs struct

Fix a crash in dm when run with Chromium command buffer driver.
Also removes glCopyTextureCHROMIUM, it does not seem to be used.
This is removed on the grounds that it would need similar change,
if it was used. The variable fCopyTextureCHROMIUM does not seem to
be populated in the Chromium side, either.

This change enables multisampled clipping for mixed sampled
render targets. Previously clipping in mixed samples config
behaved the same as in the gpu config.
In order to retrofit non-MSAA draw methods, programmable sample
locations are used in order to colocate all samples at (0.5, 0.5).

One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

This CL removes the uses of SkNEW that have resprouted since commit
385fe4d, and removes the macros entirely now that Android and Chromium
have been cleaned up to no longer depend on them.
A bunch of files implicitly depend on #include <new> from SkPostConfig.h
still though, so keep that for now. To be fixed in a followup CL.

Possible follow-up changes to consider
1. Roll SkImage_Raster and _Gpu into _Generator, where the generator (or cacherator) is backed by a pre-existing texture or raster.
2. Evolve SkImageUsageType into a verb requiring stretching, and have the caller (common code) digest the caps() and usage, so that subclasses are just told what to do (stretch or not)
3. Common code/utility to convert an unstretched texture into a stretch one (and cache it) if the generator can only make an unstretched one.
