Henrik RydgårdandClaude Opus 5.5 b684bacbc4 SoftGPU: An inf or NaN spot direction acts as the largest value of its sign

NaN and +inf directions light like (1, 1, 1), -NaN and -inf like (-1, -1, -1)
(gpu/commands/light).

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks
that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
