Radeon M7 rendering problem for SXGA+

[John Klingler]

Thanks, Alex, I'll do that.

What I was referring to by "widening" was that when setting the
RADEON_DEFAULT_OFFSET as in RADEONSetPitch() didn't work, I
followed it back to where it is called from and ended up in
the DRI code, which is quite complex.
