I don't think we need this. Some of the fields in this struct belong in
GpuMemoryBufferHandle.

We might want to rename and reuse the SurfaceTextureId struct for other types of
buffers but I prefer if we do that as a follow up when switching our surface
texture support over to gpu process creation of buffers.

I'll move the relevant fields into GpuMemoryBufferHandle, but mostly I added
this struct because PosTask ran out of variables once yuo add width, height,
etc.

Ok, hopefully not needed in the final patch but in case it is, we should try to
handle it locally instead of adding something to this file.
