divide column density texture by column density scale factor before remapping #102

that way column density limits can be in units of # of particles without the R channel going over 1. If we make the scale factor ~float precision then we can maximize the dynamic range of # of particles we can count.

I think from there it’s actually not so difficult to expose an additional scale factor that uses the resolution to convert to a number surface density in the pixel.

for a mass surface density we’d have to accumulate masses rather than 1s which might mess things up but perhaps we can vary the scale factor based off what field is being projected
