Begin: Minor refactor following fcf652f. Merging the if (Collapsed) block with the main one.

Begin: Sizing fixes regarding uses SetNextWindowSize() on individual axises.

Minor tweaks. Using ImGuiAxis defines.

Fixed 64-bit warnings.

Fixed scrollbar issue, followup to beda5fc and 2df8fa9.

Internals: Cleanup FindBestPopupWindowPos() to be more digestible, since we are bounds to rework the logic there. No functional changes intended. FIXED TYPO.

Demo: Added display for IsMouseDragging() function.

Demo: Display better mouse cursor info for debugging backends.

Exposed GetOverlayDrawList(). (~#545, ~#530)

Begin: Move the code that update the Appearing flag above the BeginDocked() branch.

Fixed scrollbar enable/disable calculation when size is modified programmatically. This is the generalization of the fix in 2df8fa9.

Lower-right resize grip only appears when hovered. (#822)

Comments about ImGuiWindowFlags_ResizeFromAnySide. Removed hovering color. May need its own color. (#822)

Windows can be resized from their borders when ImGuiWindowFlags_ResizeFromAnySide is set. (#822) The interaction is currently unsatisfying because we can only reach a window from its inner rectangle (because of HoveredWindow filtering).

Tweak four-corners resize grip code. Added ImRect::FixInverted() helper. (#822)

Added ImGuiWindowFlags_ResizeFromAnySide flag and code to resize from any of the 4 corners (only 2 corners enabled). (#822)

Update README.md

Fixed a one frame glitch, when window claiming focus themselves on appear, the title bar wouldn't use the focused color on that frame.

Internals: Splitter Behavior doesn't show a border. (#319)

Style: Tweaked default WindowRounding value from 9 to 7 (#707)

Internals: ImRect: Added IsFinite() helper.

Style: Tweaks Dark and Light styles. (#707)

Demo: Console: Fixed incorrect positioning which was hidden by a minor scroll issue (this would affect people who copied the console code as is)

Scrolling: SetScrollFromPosY() tweak to match change in a0d53fe with similar desirable jump/discontinuity at each limit to skip the (ItemSpacing>WindowPadding) difference (followup to 0e5b64e, #150)

Style, Scrolling: Fixed padding and scrolling asymetry where lower/right sides of a window wouldn't use WindowPadding properly + causing minor scrolling glitches.

Demo: Layout: Removed unnecessary BeginChild/EndChild calls

Internals: Removed unnecessary duplicate scrolling code + added extra infos to Metrics window.

Settings: Internals: Renaming.

Settings: Internals: Simplifying code a bit. Creating Settings structure during first save. Windows where ImGuiWindowFlags_NoSavedSettings was late toggled will save settings correctly. (#1000)
