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

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.

InputTextMultiline: Fixed vertical scrolling tracking glitch. ...

Fixed Travis-CI banner address.

Backends: DX10/DX11: Backup, clear and restore Geometry Shader is any is bound when calling renderer. ...

Backends: DX11: Clear Hull Shader, Domain Shader, Compute Shader before rendering. Not backing/restoring them.

OSX: Disabled default native Mac clipboard copy/paste implementation in core library (added in 1.71), because it needs application to be linked with '-framework ApplicationServices'. It can be explicitly enabled back by using '#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS' in imconfig.h. Re-added equivalent using NSPasteboard api in the imgui_impl_osx.mm experimental back-end. (#2546)

Amend 0f86116, renamed to ImGuiKey_KeyPadEnter Changelog.. (#2677, #2005)

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

Columns: Improved honoring alignment with various values of ItemSpacing.x and WindowPadding.x. (#125, #2666)

Columns: Made the right-most edge reaches up to the clipping rectangle (removing WindowPadding.x*0.5 worth of asymmetrical/extraneous padding). (#125, #2666) ...

+ Moved a few things in BeginColumns().

Revert "Columns: Improved honoring left-most and right-most alignment with various values of ItemSpacing.x and WindowPadding.x. In particular, the right-most edge now reaches up to the clipping rectangle while ensuring that the right-most column clipping width matches others. (#125, #2666)" ...

This reverts commit 6c16ba6.

Columns: Improved honoring left-most and right-most alignment with various values of ItemSpacing.x and WindowPadding.x. In particular, the right-most edge now reaches up to the clipping rectangle while ensuring that the right-most column clipping width matches others. (#125, #2666)

Columns: Fixed a regression from 1.71 where the right-side of the contents rectangle within each column would wrongly use a WindowPadding.x instead of ItemSpacing.x like it always did. (#125, #2666)

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)

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.

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)

TabBar: Fixed unfocused tab bar separator color (was using ImGuiCol_Tab, should use ImGuiCol_TabUnfocusedActive).

Fixed unnecessary test in UpdateMouseWheel() (thanks PVS). ...

TreeNodeBehavior: avoid computing bg_col for non-framed non-active tree nodes.
Comments, binaries update, minor typos.

Renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Keep redirection typedef (will obsolete).

Combo: Hide arrow when there's not enough space even for the square button. ...

+ Various todo items.

fonts/binary_to_compress: display error message when failing to open file + misc comments.

Window: Mouse wheel scrolling while hovering a child window is automatically forwarded to parent window if ScrollMax is zero on the scrolling axis. Also still case if ImGuiWindowFlags_NoScrollWithMouse is set (not new), but previously the forwarding ...

would be disabled if ImGuiWindowFlags_NoScrollbar was set on the child window, which is not the case any more (amend #1502, #1380).

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

Misc: Added IMGUI_DISABLE_METRICS_WINDOW imconfig.h setting to explicitly compile out ShowMetricsWindow(). + Internals: Minor renaming.

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

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

Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.

ImDrawListSplitter: Fixed memory leak when using low-level split api (was not affecting ImDrawList api, also this type was added in 1.71 and not advertised as a public-facing feature).
