Henrik RydgårdandClaude Opus 5.5 ce310e69a6 Keep the GE-exact FIXA/FIXB blend within fp16's range ...

Compute the product as (c+0.5) * (2f+1)/512, which is still exact in fp32, and
use mediump where highp isn't available instead of falling back to the old
blend. Simulated over all inputs, about 3% of fp16 results come out a level
too bright, against nearly half with the plain blend factors. With mediump
forced on NVIDIA's Vulkan driver (which runs it as fp16), the Split/Second
bloom dumps land within 2% of the highp result.
