Polish and add aborting to several input widgets: no Esc closing parent menus; color picker axis align; repeat on arrow buttons (#2276)

* Remove color input outline; reduce antialiasing compositing artifacts in color widgets

* Rename ColorButton to ColorInput

* Add features and aborting to several other widgets

- Prevent Esc from closing parent floating menus when aborting
- Fix missing icon regression
- Gutter resizing abort
- Color picker aborts, Shift axis alignment, improve click/drag behavior for gradient spectrum
- Scrollbar abort, repeat when held, fix directional arrows when viewport is zoomed
- Number input abort, repeat when held
