Disable with ConfigWindowsMemoryCompactTimer < 0.0f (#2636)

Added a mechanism to compact/free the larger allocations of unused windows (buffers are compacted when a window is unused for 60 seconds, as per io.ConfigWindowsMemoryCompactTimer = 60.0f). Note that memory usage has never been reported as a problem, so this is merely a touch of overzealous luxury. (#2636)

Demo: PlotLine example displays the average value. (#2759) + extra comments

SliderScalar: Improved assert when using U32 or U64 types with a large v_max value. (#2765) ...

+  misc minor stuff.

Rebased imstb_rectpack on stb_rect_pack v1.00.

Internals: Storing settings using ImVec2ih to match what we are doing with dock node. + removed ImMax from reading Size value (done in Begin) + removed seemingly unnecessary FLT_MAX compare in SettingsHandlerWindow_WriteAll. ...

About: Added backquote to text copied into clipboard so it doesn't mess up with github formatting when pasted.

ImDrawList: clarified the name of many parameters so reading the code is a little easier. (#2740)

Using offsetof() when available in C++11. Avoids Clang sanitizer complaining about old-style macros. (#94)

More typos in comments (#2738)

TabBar: fixed single-tab not shrinking their width down. ...

+ minor typo fixes (#2738)

Internals: Renaming window size calc functions.

TabBar: fixed ScrollToBar request creating bouncing loop when tab is larger than available space.

ColorPicker: Made rendering aware of global style alpha of the picker can be faded out. (#2711) ...

Note that some elements won't accurately fade down with the same intensity, and the color wheel when enabled will have small overlap glitches with (style.Alpha < 1.0).

Removing Funding file (unnecessary as we'll switch services)

Create FUNDING.yml

Explicit narrowing cast from size_t to UINT (#2726) ...

Clang: `non-constant-expression cannot be narrowed from type 'size_t' (aka 'unsigned long long') to 'UINT' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]`

Backends: Vulkan: Added support for specifying multisample count. (#2705, #2706)

Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count, would generally make the debug layer complain (Added in 1.72).

Version 1.73 WIP

Internal: Made ScrollToBringRectIntoView() handle recursing back to scroll parent window, so the function can be called elsewhere (instead of 1 deep recursion done in NavUpdateMoveResult().

Version 1.72b (patch for nav)

Nav: Made hovering non-MenuItem Selectable not re-assign the source item for keyboard navigation.

Scrolling, Nav: Fixed programmatic scroll leading to a slightly incorrect scroll offset when the window has decorations or a menu-bar (broken in 1.71). This was mostly noticeable when a keyboard/gamepad movement led to scrolling the view, or using e.g. SetScrollHereY() function. Fix/amend a0994d74.

Internal refactor: moved all Scroll related functions in a same spot.

Internal: Moved NavScrollToBringItemIntoView() declaration to imgui_internal.h. Fixed spacing missing in 494d804. Fixed changelog wreck from 1.72.

Internal: Avoid using GImGui multiple times in same function.

Internal: Added ImGuiInputTextState::ClearText() helper.

Nav: Fixed an issue with NavFlattened window flag where widgets not entirely fitting in child window (often selectable because of their extruded bits) would be not considered to navigate toward the child window. (#787) ...

This creates a little bit of tension because g.NavDisableHighlight tends to makes the reference point not always visible.
