> > > This adds support for mailboxes to ScopedWriteLockGL. Using the mailbox
> > > requires using ScopedTextureProvider/ScopedSkSurfaceProvider which
> > > ensures that the texture id for the mailbox is destroyed after use on
> > > the worker context.
> > >
> > > This CL also includes the following cleanup:
> > > 1. ResourceProvider locks don't keep resource pointers around.
> > > 2. ScopedSamplerGL does not inherit from ScopedReadLockGL.
> > > 3. GpuRasterizer is folded back into GpuRasterBufferProvider.
> > > 4. TileTaskManager does not own RasterBufferProvider.
