- input: rework IO to be able to pass actual events to fix temporal aliasing issues.
- input: support track pad style scrolling & slider edit.
- memory: add a way to discard allocs of unused/transient windows. with the current architecture new windows (including popup, opened combos, listbox) perform at least 3 allocs.
- misc: mark printf compiler attributes on relevant functions
- misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- style editor: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space?
