[Mesa-dev] [PATCH] u_tile: fix stencil texturing tests under softpipe

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

arb_stencil_texturing-draw failed under softpipe because we got a float
back from the texturing function, and then tried to U2F it, stencil
texturing returns ints, so we should fix the tiling to retrieve
the stencil values as integers not floats.
