Version 1.63

Comments, demo

Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete fast as IsItemDeactivatedAfterChange() is very recent). (#820, #956, #1875, #2034)

Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool returned by most widgets. It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034)

Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2035, #2006, #1443, #1008)

InputText: callback InsertChars() support resize callbacks correctly (followup to 24ff259) + fixed demo to use those functions. (#2006, #1443, #1008).

InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).

InputText: Internal renaming of some fields + final copy uses edit_state.CurLenA+1 instead of buf_size.

Use literals in place of LLONG_MIN, LLONG_MAX ULLONG_MAX if they are not available. Amend 498c0dc. We prefer using the defines if available in limits.h because they somehow tend to work without warnings when enabling strict C++03 compilation. The 3 literals are fallbacks.. (#1926).

Renamed io.OptResizeWindowsFromEdges to ConfigResizeWindowsFromEdges, io.OptCursorBlink to io.ConfigCursorBlink, io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. (#1427, #1495, #822, #473, #650) ...

Demo: Exposed flags in Demo.

Demo: Fix using ambiguous InputFloat() call which redirect to obsolete version. (#1990)

Fixes for pre-C++11 compilers. ...

That said, I think we can consider upgrading requirement to an early VS-friendly subset of C++11. The thing I would like the most from C++11 are forward-declared enum (from VS 2012 onward).

Visual Studio: calling into _vsnprintf. (#1085)

Demo: Added extra demo in the Basic Horizontal Layout section. (#1977) + PR guidelines

Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.

Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section. This will be of more importance with the introduction of tabs.

Demo: Fixed spacing from b629f90 change.

Examples: Tweaked the main.cpp example structure for all examples. (There are a few hidden agendas here: 1) I would like to avoid encouraging people from using the implicit "Debug" window, and promote using Begin/End. In spite of my best attempt, there are a few feature of the upcoming docking system that cannot work 100% properly for the implicit Debug window, so future proof let's not put that feature in the spotlight too much for new users. 2) Moved dumb hardcoded positions into a single spot that can be replaced with a viewport relative position and not affect other demo windows. 3) Calling ShowDemoWindow before anything else, also for the benefit of a specific docking demo which will have an ordering constraint which is not really problematic in a real app but shouldn't be put forward in the demo.

Demo: Spacing.

Demo: Re-ordered example app code to match their menu order and forward declaration order + added header to delimitate them.

Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. (#787)

Examples: Comments, Demo: Log early out, TODO. (#1553)

Demo: Added basic Drag and Drop demo. (#143, #1931)

Fixed software Hand cursor from not actually working. Fixed demo from crashing. Fixed typo and extraneous trailing space. Added Changelogs. (#1913, #1914)

ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat). Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.

Version 1.63 WIP

Demo: Fixed incorrect response to Begin() returning false in overlay demo (which cannot happen since we don't have a title bar, but that doesn't make it a good behaving demo!).

Demo: Fixed mismatched TreePush/TreePop in Property Editor, due to incorrect revert in 826d771 (#1895)

Version 1.62

Revert 640c0566: TreeNode: Fixed nodes with ImGuiTreeNodeFlags_Leaf flag always returning true which was meaningless -> more flexible to keep allowing it by default so it setup an ID scope.
