After #957 colormaps for textures no longer clamp on the min value, but this occurs only on lavapipe.

For example, here the colorbar on the right is an Image with a Texture that contains values between -51 (bottom of the bar) to 303 (top of the bar). The image material clim is (0.0, 255.0). The values below zero should be black.

Correct image:

Weird thing is this issue is only on lavapipe on github actions, the mac runners do not produce this issue and I can't produce this locally on any GPU (integrated, nvidia, AMD).

I tried using lavapipe locally but getting segfaults, I'm on debian 11 will try on a newer OS tomorrow.
