Fix multiple bugs surrounding parameter ranges. (-> Fixes every dimension maximum being off-by-1 in the visualization.) Fix multiple rendering bugs. (-> Fixes grey pixel artifacts at cube edges in multiple scenarios.) Fix animation settings window not disappearing on touch/mouse hybrid devices. Bump to v0.4.23.
