-/**
- * \name GLSL uniform arrays and structs require special handling.
- *
- * The GL_ARB_shader_objects spec says that if you use
- * glGetUniformLocation to get the location of an array, you CANNOT
- * 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
- * of the array with glUniform().
- *
- * 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 creating multiple entries for uniform arrays
- * in the UniformRemapTable so that their elements get sequential locations.
- *
- * Utility functions below offer functionality to split UniformRemapTable
- * location in to location of the uniform in UniformStorage + offset to the
- * array element (0 if not an array) and also merge it back again as the
- * UniformRemapTable location.
- *
