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)

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

+ minor typo fixes (#2738)

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).

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

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: 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

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.
