[PyOpenGL-Users] Reading Depth Component - not working anymore?

[Hart's A. <bha...@ya...>]

I am using the latest pyopengl (ctypes based) release for Ubuntu Gusty.  I am unable to read the
zbuffer using glreadpixels GL_DEPTH_COMPONENT, my function had worked before with the much older
pyopengl2.x series.  I'm not sure if this is a bug in new ctypes-pyopengl or is it my ATI drivers
not supporting that feature.  I'm wondering if anybody has had any luck doing this?  One note is
that i can read the zbuffer directly into a texture (for shadows) with no problem using glCopyTexSub2d.
