- * GLGL uniform arrays and structs require special handling.

- * The GL_ARB_shader_objects spec says that if you use

- * access other elements of the array by adding an offset to the
- * returned location. For example, you must call
- * glGetUniformLocation("foo[16]") if you want to set the 16th element

- *
- * HOWEVER, some other OpenGL drivers allow accessing array elements
- * by adding an offset to the returned array location. And some apps
- * seem to depend on that behaviour.
- *
- * Mesa's gl_uniform_list doesn't directly support this since each
- * entry in the list describes one uniform variable, not one uniform
- * element. We could insert dummy entries in the list for each array
- * element after [0] but that causes complications elsewhere.
- *
- * We solve this problem by encoding two values in the location that's
- * returned by glGetUniformLocation():
- * a) index into gl_uniform_list::Uniforms[] for the uniform
- * b) an array/field offset (0 for simple types)
- *
- * These two values are encoded in the high and low halves of a GLint.
- * By putting the uniform number in the high part and the offset in the
- * low part, we can support the unofficial ability to index into arrays
- * by adding offsets to the location value.
