[Mesa-dev] [PATCH] i965: Enable tiled mem_copy with sRGB-formatted resources

From: Nanley Chery <nanley.g.chery at intel.com>

RGBA8 and BGRA8 unorm formats are compatible with the various
mem_copy functions. Their sRGB counterparts are also compatible
because they're also color-renderable (of importance when the
specified resource is a readbuffer) and they share the same
physical layout.
