[HOpenGL] Blend equations

[Gunnar Kedenburg]

Hi,

blendEquation $= ... has no effect on my system, ghc 6.4.1/6.4.2 with
this GL implementation:

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 6600 GT/PCI/SSE2/3DNOW!
OpenGL version string: 2.0.2 NVIDIA 87.56

It works from C though.

By the way, it would be so great to have GLSL support in HOpenGL. Any
chance to see it soon?

Thanks,
Gunnar.
