[Chromium-dev] image compression

[Dale B. <dr...@cs...>]

I'm looking at doing image compression in the readback spu and I wanted to
propose this to see if there are any problems I'm overlooking.  The basic
plan would be to modify readback to convert the framebuffer to YV12 (using
the color matrix to convert to YUV first), compress it, let the pack spu
send the buffer with DrawPixels, and then modify the render spu to
decompress the data before drawing.  It seems pretty straightforward, but
I'm sure there are aspects I haven't thought about yet.  If anyone can
foresee why this would be a problem, please let me know.
