Thanks for digging and verifying my suspicion. Too bad; many features in
GL3 are available as extensions in GL2, which really eases the porting
effort. However, looks like clipping is just one of those cases where
the code has to change between versions.

Hi all -- Does anyone know of an OpenGL extension to GL 2.x that adds
the clip distance feature found in GL 3 / GLSL 1.30? It does not
appear to be in ARB_gpu_shader4...
I can't find it in the registry anywhere. There's a mention of it in
NV_transform_feedback, but I don't think that's what you're after. In
the newest glext.h, it's protected by the GL_VERSION_3_0 symbol and
nothing else.
There may not be one. I don't think there was any formal requirement to
expose every new feature in GL 3 as an extension in GL 2.
