Subject: drirc: add force_glsl_abs_sqrt() for "Spec Ops: The Line"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Game ported from D3D9 which expects sqrt() to compute the absolute
value as explained in the spec.

This gets rid of the NaN values as well as the black squares
with RadeonSI.
