Activating widget bring parent window to front

  - widgets: switching from "widget-label" to "label-widget" would make it more convenient to integrate widgets in trees
  - widgets: clip text? hover clipped text shows it in a tooltip or in-place overlay
  - widgets: checkbox/radio active on press, is that standard/correct ?
- - widgets: widget-label types of function calls don't play nicely with SameLine (github issue #100) because of how they intentionally not declare the label extent. separate extent for auto-size vs extent for cursor.
  - widgets: IsItemHovered() returns true even if mouse is active on another widget (e.g. dragging outside of sliders). Maybe not a sensible default? Add parameter or alternate function?
- - widgets: activating widget doesn't move parent to front
  - main: make IsHovered() more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
  - main: make IsHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
  - scrollbar: use relative mouse movement when first-clicking inside of scroll grab box.
