Remove trailing spaces (grep for ' \r?$' in visual studio)

Columns: Separator: Fixed a bug where non-visible separators within columns would alter the next row position differently than visible ones. ...

Fixed rounding issues also leading to change of ScrollMax depending on visible items (in particular negative coordinate would be rounded differently)

TabBar: feed desired width (sum of unclipped tabs width) into layout system to allow for auto-resize. (#2768) ...

Before 1.71 tab bars fed the sum of current width which created feedback loops in certain situations. Amend f95c77e.

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

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)

More typos in comments (#2738)

Version 1.73 WIP

Version 1.72b (patch for nav)

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

Version 1.73 WIP

Version 1.72

Internal: Added IsMouseDragPastThreshold(). Tweaks. Todo. ...

Demo: Showing how to use the format parameter of Slider/Drag functions to display the name of an enum value instead of the underlying integer value

ImDrawList: Using ImDrawCornerFlags instead of int in various apis. ...

Demo: Using ImGuiColorEditrFlags instead of int.

Scrolling: Made it possible for mouse wheel and navigation-triggered scrolling to override a call to SetScrollX()/SetScrollY(), making it possible to use a simpler stateless pattern for auto-scrolling. ...

Demo: Log, Console: Using a simpler stateless pattern for auto-scrolling.

Columns: Made GetColumnOffset() and GetColumnWidth() behave when there's no column set, consistently with other column functions + fixed Columns demo (#2683)

Columns: Fix support for BeginColumns() with a count of 1 (not that this isn't available via the old Columns() api). Tweaked Demo to facilitate testing for it.

Misc: Made Button(), ColorButton() not trigger an "edited" event leading to IsItemDeactivatedAfterEdit() returning true. This also effectively make ColorEdit4() not incorrect trigger IsItemDeactivatedAfterEdit() when clicking the color button to open the picker popup. (#1875) ...

Demo: Added Button with repeater and InputFloat with +/- button to the status query test demo.

Fixed old SetWindowFontScale() api value from not being inherited by child window. Added comments about the right way to scale your UI (load a font at the right side, rebuild atlas, scale style). ...

+ Added missing IMGUI_API marker to the EmptyString storage used by ImGuiTextBuffer. (#2672)

Style: Added style.ColorButtonButton (left/right, defaults to ImGuiDir_Right) to move the color button of ColorEdit3/ColorEdit4 functions to either side of the inputs.

Removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). (#581, #324)

Moved ImGuiColumnsFlags erroneously forward declared in imgui.h + demo bit.

Scrollbar: Avoid overlapping the opposite side when window (often a child window) is forcibly too small.

Added SetScrollXHere, SetScrollFromPosX: Changelog, demo, comments (#1580).

Internals: ImGuiListClipper using absolute coordinate (instead of relative one). Minor no-op tweaks + ImDrawListSplitter assert

Demo: Using ImVec2(-FLT_MIN,0.0f) instead of ImVec2(-1.0f,0.0f) where it makes sense. (#2449)

Disable -Wpragmas warning in GCC to avoid relying on version checks, as unusual/forks/mods don't appear to always have same warning<>version. (#2618) ...

+ Fix version number in imgui.h
