  ISSUES AND TODO-LIST
 
  - misc: merge ImVec4 / ImGuiAabb, they are essentially duplicate containers
- - 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
  - window: autofit is losing its purpose when user relies on any dynamic layout (window width multiplier, column). maybe just discard autofit?
  - window: support horizontal scroll
  - window: fix resize grip scaling along with Rounding style setting
  - 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
+ - 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.
  - input number: optional range min/max
  - input number: holding [-]/[+] buttons should increase the step non-linearly
