// Even though the specified locations overlap, the spec says that a *link*
// error is generated. The changes to section 3.9.2 say:
//
// "Output binding assignments will cause LinkProgram to fail:
//
// * if the number of active outputs is greater than the value of
// MAX_DRAW_BUFFERS;
//
// * if the program has an active output assigned to a location
// greater than or equal to the value of
// MAX_DUAL_SOURCE_DRAW_BUFFERS and has an active output assigned
// an index greater than or equal to one;
//
// * if more than one varying out variable is bound to the same
// number and index; or
//
// * if the explicit binding assignments do not leave enough space
// for the linker to automatically assign a location for a varying
// out array, which requires multiple contiguous locations."
