- input number: use mouse wheel to step up/down

- input text: add multi-line text edit

- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 horrible layout code. item width should include frame padding, then we can have a generic horizontal layout helper.

- 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
