now you can modify the colors used to render different parts of the keycaps! This will be used in some examples to draw ghostly outlines of components.
Also make the keytop width changes less dramatic, by centering them around the center of the sides of the keycap. Now instead of choosing the front or back of the keycap and shrinking / expanding the back or front to fit, we shrink / expand both evenly. This actually cleans up the logic too! hooray.
make square_shape and rounded_square_shape use trapezoids as their top surface, perfectly shaped so that the sides of the keycap are flat, and can be used as a printing surface
not sure where but `depth_difference` for `shape()` is being left out. defaulting to 0 (which should be fine for a delta variable anyways) fixes the issue
I'm at a bit of a crossroads as without the elephant's foot brought about by printing the keycaps right side up, with no stem inset, I can print these stems with no inner slop and they fit _fantastic_. But we've had slop in the stem for printing right-side-up since inception, so switching now is probably not a good idea. this warning might be good enough
now you can do stuff like:
```
gherkin_bump_layout("g20") {
upside_down() key();
};
```
and it'll work! you still have to specify the profile in the layout itself because row and column are not special variables... hm
rediscovered my old keysets file, adapted the functionality to make a flexible base layout tool.
also tweaked double sculpting to generically sculpt to both hands. it works, but it still needs more refinement, and the best layouts are going to be hand-generated anyways
