- input number: holding [-]/[+] buttons should increase the step non-linearly
- input number: rename Input*() to Input(), Slider*() to Slider() ?
- layout: clean up the InputFloat3/SliderFloat3/ColorEdit4 horrible layout code. item width should include frame padding, then we can have a generic horizontal layout helper.
- add input2/4 helper (once above layout helpers are in they'll be smaller)
- add input4 helper (once above layout helpers are in they'll be smaller)
- columns: declare column set (each column: fixed size, %, fill, distribute default size among fills)
- columns: columns header to act as button (~sort op) and allow resize/reorder
- columns: user specify columns size
