IMO, MAX_xxx_UNIFORMS should be checked against the number of active uniforms,
and not all those declared. Otherwise it would be limiting beyond the
capabilities of the cards. And if the r300 compiler optimized that uniform
away, it means it effectively is not active, even if the GLSL linker thinks so.

So, IMO, either the GLSL compiler does the optimization, or it grows the
ability to query how many uniforms are actually active in the driver.

But hopefully it shouldn't be hard to make the optimization in the GLSL, and
therefore avoid backward notificiation calls.
