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

Nav, Scrolling: Added support for Home/End key. (#787)

Fixed missing IMGUI_API for IsMouseDragPastThreshold().

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.

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)

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.

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: Added ImGuiInputTextState::ClearText() helper.

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

Internals: Added IMGUI_DEBUG_INI_SETTINGS. Made IMGUI_DEBUG_LOG redefinable in imconfig.h. Comments. Fix to allow Metrics's NodeWindow() being called with a NULL window.

Internals: Merge in minor noise from wip Tables branch to simplify further merging.

Scrolling: Made mouse-wheel scrolling lock the underlying window until the mouse is moved again or until a short delay expires (2 seconds). This allow uninterrupted scroll even if child windows are passing under the mouse cursor. (#2604)

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.

Debug Tools: Added DebugStartItemPicker() in imgui_internal.h to facilitate binding this anywhere in user's tool. Adedd highlight. Added IMGUI_DEBUG_TOOL_ITEM_PICKER_EX to break in ItemAdd().

Internals: Refactor: Moved all Columns code from imgui.cpp to imgui_widgets.cpp (#125) ...

Also moved NextColumn between BeginColumn and NextColumn which makes it easier to work on that code.

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)

Debug, Metrics: Added "Tools->Item Picker" tool which allow clicking on a widget to break in the debugger within the item code. The tool calls IM_DEBUG_BREAK() which can be redefined in imconfig.h if needed.

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

Internals: Checkbox: Added undocumented mixed/indeterminate/tristate support via ImGuiItemFlags_MixedValue. (#2644)

Internals: Renamed GetFrontMostPopupModal() to GetTopMostPopupModal() to be consistent. Renamed other locals to follow that terminology.

Internals: Columns: Poke into WorkRect and use them in the GetContentRegionMax() functions. This should be a no-op, but preparing us to transition toward using WorkRect instead of ContentRegionRect. ...

Removed one use of ContentsRegionRect.

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
