_mesa_ClearColor() is called by glClear().

However, if you're currently building a display list (i.e.: 
glNewList/glEndList) then glClear() will call save_ClearColor() instead.

There's a "dispatch" layer that lives between the glFoo interface 
functions and the actual implementation of them inside Mesa.
