The raster and video tests seem to be failing because of small pixel differences. I'm not sure why since they pass locally. I'm guessing this may be due to different devices calculating the pixels slightly different during reprojection. Is the best approach to this to add a pixel tolerance to these tests or should we try to make it more determinant?

Looking at the render tests I think so. I might need this PR merged soon to be able to do a sane rebase from main to globe-view, there will be a lot of conflicts that would be hard to reason about without the validation of render tests.

This is so great. Really thorough
