Re: Rendering to texture

Hi,

I have patches against an older version of the OpenGL library (namely,
2.2.1.1),
which introduce the necessary functionality:

http://code.haskell.org/~bkomuves/hopengl_2009-03-13.patch

Render to texture works pretty well with that (except that some drivers
crash sometimes
when querying the framebuffer status...). The FBO part is in the module

Graphics.Rendering.OpenGL.GL.FBO

For example the C call `glBindFramebuffer' will become the statevar
`framebufferBinding'.

However, these patches are incompatible with the newer versions of the
OpenGL binding,
which builds on OpenGLRaw; probably it wouldn't be too much work to port
them, but
I haven't had time to investigate that.
