- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
- window: investigate better auto-positioning for new windows.
- window: top most window flag? (#2574)
- window: the size_on_first_use path of Begin() can probably be removed
- window/size: manually triggered auto-fit (double-click on grip) shouldn't resize window down to viewport size?
- window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. -> this may require enforcing that it is illegal to submit contents if Begin returns false.
- window/child: background options for child windows, border option (disable rounding).
