  ==================
 
  - misc: merge or clarify ImVec4 vs ImRect?
- - window: add horizontal scroll
  - window: fix resize grip rendering scaling along with Rounding style setting
  - window: autofit feedback loop when user relies on any dynamic layout (window width multiplier, column). maybe just clearly drop manual autofit?
  - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. 
  - window: allow resizing of child windows (possibly given min/max for each axis?)
  - window: background options for child windows, border option (disable rounding)
  - window: resizing from any sides? + mouse cursor directives for app.
+ - scrolling: add horizontal scroll
+!- scrolling: set scrolling given a position.
+!- scrolling: allow immediately effective change of scroll if we haven't appended items yet
  - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
  - widgets: clean up widgets internal toward exposing everything.
  - main: considering adding EndFrame()/Init(). some constructs are awkward in the implementation because of the lack of them.
  - main: IsItemHovered() make it 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: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
  - input text: add ImGuiInputTextFlags_EnterToApply? (off github issue #218)
+!- input text: multiple lines inputs (#200)
 !- input number: large int not reliably supported because of int<>float conversions.
  - input number: optional range min/max for Input*() functions
  - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
