[Mesa-dev] [PATCH 2/2] i965/blorp: Fix narrowing warnings.

Blorp has to convert rectangle coordinates from integers to floats in
order to send them down the GPU pipeline. Recent versions of GCC
issue a warning for this, since a float is not capable of precisely
representing all possible 32-bit integer values. Suppress the warning
with an explicit type cast in the case of blorp, since rectangle
coordinates will never be large enough to cause a loss of precision.
