[Intel-gfx] A non-3D program which doesn't work with the intel driver

[Philipp Klaus Krause]

A long time ago I tried to write a ColecoVision emulator, but abandoned
the project after some time. It uses OpenGL for graphics output (mostly
glBitmap and glDrawPixels, no 3D stuff).
I just tried to run it using 2.1 Mesa 7.3-rc3 from debian experimental,
but it don't see any graphics output (window stays as if I never
rendered to it). It works fine with LIBGL_ALWAYS_INDIRECT=1.
