Here's a one-liner fix, which will cause CLIPSPAN hopefully never return

Ian, what do you think? Would it be better to have the optimized
read/write functions deal with negative values instead?
Ah crap those UNLOCK_HARDWARE changes of c

That was my first thought, too (moving the window out to the left...) ;-)
This is no problem for the generic

Move window 'out' to the left.
NO sigfault with MESA_NO_SSE and MESA_NO_MMX.
With MMX:

Move window 'out' to the left.
NO sigfault with MESA_NO_SSE and MESA_NO_MMX.
