Apparently the quantization math isn't cheap. This further reduces overhead by 2% for drawoverhead/8 textures. The improvement is measured by looking at the sysprof percentage delta and multiplying by 2 (because we have the frontend and gallium threads with equal overhead, so the benefit is doubled compared to 1 thread). Both per-sampler and per-unit lod bias values are quantized. The difference in behavior is that both values are quantized separately and then added up, instead of first added up and then quantized. The worst case error is +- 1/256 in the reduced precision, i.e. off by one in a fixed-point representation, which should be fine.
