[Mesa-dev] [PATCH] st/mesa: treat 1D ARRAY upload like a depth or 2D array upload.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This is because the HW doesn't always store a 1D array like a
2D texture, it more likely stores it like 2D texture (i.e.
alignments etc).

This means we upload each slice separately and let the driver
work out where to put it.
