Also updates the Blender script.

It can now generate views on a per-object basis, and uses
whole collections so that many objects can be grouped together.

Also add some tweaks to the process-model script that I managed to lose.

Entities derived from models can now have volumes

Also adjust Rose's mass

This also updates the model-processing script to automatically
insert the model data into the appropriate source file.

I also significantly rewrote the process-potrace-model-forms.py
script, as well as the blender-model.py script. Most of the other
scripts are old; I removed some personal info from them, so they
don't work properly now.

Two things: One, some states were getting simplified
out of existence. Two, states that crossed the -180/180
longitude line were getting projected from the wrong side
of the planet.

Also add some missing scripts

Also fix up the bounds script to delete old files

Also update the add-bounds script to also
rename files

This also includes new scripts for generating some data -- but I am going
to migrate the actual generator scripts to another repo soon

This one doesn't require autotracing the lines, which should make
for better results.

Also adds the scripts used to generate them.

Firefox won't draw SVGs to a canvas correctly without width/height
attributes (even if a viewBox is present). This commit inserts those
values where needed and removes the Firefox check from the click
detection code, so it works properly (and screenshots are fixed, too).
