 TODO:
-  * Make flat stem support default
+  * implement key_shape_at_progress which allows you to query for the exact 2d outline of the keycap at a given height
+    * this makes certain functions easier - building the envelope for instance
+    * requires breaking out shape_slice, and creating a polygon of the skin_shape_slice slices
+  * dishes add / remove height from keycaps, particularly spherical dishes
+    * a bandaid solution would be to allow you to modify where the keytop is along the progression of the keycap
+      * you can't just set a new total_depth because of how width_difference and height_difference work
+    * the true solution would be to rewrite how the dishes work to make them very graduated at the edges
   * implement regular polygon for skin extrusions
   * switch to skin-shaped extrusions by default
   * kailh choc has a non-square key unit; should I get that working for layouts etc?
