  - 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
