program intel->front_pitch as the stride for the hardware, not the screen width.
This prevents us from programming the hardware with the wrong value since the
shadow buffer stuff messes with scrn->displayWidth. From kettenis@.
(oga; i think i've seen bugs in relation to this with multihead and
tiling framebuffers, too)
