[HOpenGL] Querying GL info, including # of texture units.

I'm looking for a way to query the number of available texture units to
shaders.  In C, I think the value can be extracted with
in GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.  There are also getInteger1
and GetMaxCombinedTextureImageUnits in
Graphics.Rendering.OpenGL.GL.QueryUtils, but that module isn't exported from
the OpenGL package.

Have I missed something?
