static GLboolean compatible_program_targets ( GLenum  t1,
GLenum  t2 
) [static]

Mixing ARB and NV vertex/fragment programs can be tricky.

Note: GL_VERTEX_PROGRAM_ARB == GL_VERTEX_PROGRAM_NV but, GL_FRAGMENT_PROGRAM_ARB != GL_FRAGMENT_PROGRAM_NV The two different fragment program targets are supposed to be compatible to some extent (see GL_ARB_fragment_program spec). This function does the compatibility check.
