Oooh, is this tool for visualizing errors in cost, gradient, Jacobian, etc online anywhere? :)

This is a useful tool for visualizing errors in cost, gradient, Jacobian, and results; but I don't remember it well, and that means no one else probably knows it exists, since I made it...

The tool is literally a program that loads in all of our ".imagedump" files from a folder, creates difference and quotient images and lets you tweak visualization of each one using the built-in G3D texture viewer. I don't think it'd be that generally useful for non-image based solvers; though anything could be displayed as an image even if its 1D.

If for some reason that sounds useful to you, the code is in the ImageDumpViewer folder of this repo, but is not yet user-friendly unless the user is me (and even then not really). If you have some use for it I'll move making it user-friendly up my priority list. (You could probably make a python script that does the same thing and doesn't require G3D in an afternoon though).
