Bug detailed description:
--------------------------
This issue doesn't happen in software rendering mode.
And, q965 doesn't have this issue.
glBitmap is affected by a glDrawPixels call before it.
Pls try the attached test case
Reproduce steps:
----------------
start X
compile and run the attached test case
Current result:
----------------
after drawpixel, read out pixels: (0, 0) = (0.000000, 0.000000, 0.000000)
after glBitmap, read out pixels: (0, 0) = (0.027451, 0.027451, 0.027451),
should be (1.000000, 1.000000, 1.000000)
Expected result:
----------------
glBitmap should work correctly
