[Chromium-dev] readback SPU and CR_SUPPRESS_SWAP_BIT

[Brian P. <br...@tu...>]

I know it's a bit late, but I'm looking at changing the readback SPU's 
SwapBuffers() function to ignore the CR_SUPPRESS_SWAP_BIT flag (i.e. 
no longer turn off that bit when calling the child SPU's SwapBuffers()).

Back in September, Joel Welling raised an issue with the behaviour of 
SwapBuffers, CR_SUPPRESS_SWAP_BIT and the saveframe SPU.  Modifying 
the readback SPU to pass the CR_SUPPRESS_SWAP_BIT bit unchanged fixes 
the problem, but making this change requires some small updates to the 
psubmit and CRUT demos.

I can elaborate if anyone wants more details.  I'll hold off on 
checking in my changes until tomorrow to see if anyone has any 
concerns with this change.
