Overview

Shoes' widgets, drawn by hand.

libui does have real native buttons and entries, but it can only stack them in boxes and grids -- there is no container that puts a control at an arbitrary (x, y). Shoes' whole layout model needs exactly that, so Clogs paints its widgets into the same area as everything else. The trade-off is noted in docs/libui_shoes_coverage.md: these look like Shoes widgets, not like the host platform's.
