EXA pixmap alignments.

[Thomas Hellstrom]

Hi!

EXADriverPtr->card.pixmapOffsetAlign = ?
EXADriverPtr->card.pixmapPitchAlign = ?

Is there a chance to have the above parameters defined also for system 
to frame-buffer transfers?

For example Unichrome / Unichrome Pro currently requires both to be 16 
for PCI DMA to work, and as briefly discussed on the dri-devel list, 
system / frame-buffer bounce buffers to fix alignments may be very 
undesirable.
