- input number: use mouse wheel to step up/down
- input number: non-decimal input.
- layout: horizontal layout helper (github issue #97)
- layout: more generic alignment state (left/right/centered) for single items?
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
- columns: separator function or parameter that works within the column (currently Separator() bypass all columns)
- columns: declare column set (each column: fixed size, %, fill, distribute default size among fills)

- 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?
- style editor: color child window height expressed in multiple of line height.
- optimization/render: use indexed rendering to reduce vertex data cost (for remote/networked imgui)
- optimization/render: move clip-rect to vertex data? would allow merging all commands
