This is specific to ARB as well.
The intention was to use it to deal with broken gl_ClipVertex support on Apple drivers - ie, to add the same texcoord based clipping to GLSL as a fallback if gl_ClipVertex does not work. Now you already said you considered this something Apple should fix - my point is just that the clipplane search code is not useless for GLSL
I t could of course be moved, if needed.
