[ProtonAOSP] blur: Reduce floating-point precision for UV coordinates
While blur rendering is mostly memory-bound, reducing ALU utilization is
still helpful. This doesn't result in any noticeable artifacts in the
blurred image.
When tested with 2 layers of another 6-pass blur implementation, this
saves ~50 µs of rendering time on an Adreno 640 GPU at 1440x3040
resolution.
