Giovanni Mascellani 8efbd4de51 tests: Work around a rounding difference between NVIDIA and AMD.
NVIDIA and AMD round differently the assignment of 0.5f to a UAV
of type R16G16_UNORM. NVIDIA rounds to 0x7fff and AMD to 0x8000.
According to both Vulkan and D3D12 specifications, both values
are acceptable, but the discrepancy currently appears as a
failure on NVIDIA cards.

Work around the issue by using 0.25f instead of 0.5f, which is
rounded as 0x4000 on both implementations.
