I haven't checked if this is the case here, but the NVidia driver disables CSAA
and switches to slower(?) MSAA when you call glClear to clear only a part of
the buffer (glClear is affected by the scissor rectangle).

The driver logs a message to the GL_ARB_debug_output log when CSAA is
deactivated, but creating a debug GL context is difficult in SDL 1.2.
