Detailed Description

This is a generic attachment class for out GrSurfaces. It always represents a single gpu allocation. It contains usage flags so that we know what the attachment can be used for.

TODO: Once we can pull out GrRenderTarget to be more of a framebuffer and break apart our texture render target diamond, we will merge this class with GrSurface. Until then this will act as the staging class for the new surface and framebuffer world.
