Selectable() should have an ID even though they are disabled, to be consistent with other widgets. Not sure of the reasoning ~1.41 which made this turn to 0.

Fixed animated window titles from being updated when displayed in the CTRL+Tab list. + Adding overkill helpers for reusing buffers. (#787)

Merge branch 'master' into viewport ...

# Conflicts:
#	imgui.cpp
#	imgui.h
#	imgui_internal.h

Tabs: Added ImGuiTabBarFlags_NoTooltip flag. (#261, #351) + added helpful assert

Demo: Log: Comments. Using clipper. Not linking with rand() anymore.

Tweak changelog + tweak internal render helper functions.

Renamed ImFont::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Keep redirection typedef (will obsolete).

Comments/formatting on obsolete stuff

IO: Renamed InputCharacters[], marked internal as was always intended. AddInputCharacter() goes into a queue which can receive as many characters as needed during the frame. This is useful for automation to not have an upper limit on typing speed. Will later transition key/mouse to use the event queue later.

Moved ImVector higher up in imgui :( because we will need it in ImGuiIO.

Added alternative Rust bindings

Nav: Fixed an keyboard issue where holding Activate/Space for longer than two frames on a button would unnecessary keep the focus on the parent window, which could steal it from newly appearing windows. (#787)

Added bindings in Readme. Added internal IMGUI_DEBUG_LOG() helper. Comments, missing breaking changes note relative to imgui_impl_xxxx changes, not really part of core but worth adding in the imgui.cpp breaking change section.

Examples: Allegro 5: Properly destroy all globals on shutdown. (#2262)

Added sanity check to debug parent/child ordering issues (they would generally manifest with an assert/crash in EndFrame bu tthis assert will catch some earlier).

(Breaking change) Reorganized Viewports advanced flags, moved into new io.ConfigViewportsXXX flags. Pay attention that ImGuiConfigFlags_ViewportsDecoration became ConfigViewportsNoDecoeration, so the value is inverted! (#1542)

Viewport: Added ConfigViewportsNoParent to parent viewport default to NULL and not main viewport. Fix eg.. popups appearing erroneously focusing parent window.

Viewport: Fix for minimization of individual viewports (the current back-end forcing a parent/child relationship between secondary viewports and the main viewport have hidden this issue). Follows d8ab2c1ac.

Viewport: Fixed minimization of main viewport leading to it being omitted from platform_io.Viewport list where the users assume it is at index 0. Fix d8ab2c1ac. It wasn't a problem when other viewports were child of the main viewport because they would all be minimized together. (#1542)

Natvis: Added Hidden info about ImGuiWindow.

Viewport: Added minimum viable information in the Changelog.

Examples: Downgrading projects to xcode 9.2 (maybe 8.0) (#2134) ...

* example_apple_opengl2: The deployment target was set to 10.12 from XCode 9.2.
* imgui_impl_metal: header not found by XCode 9.2.
* example_apple_metal: The deployment target was set to 10.12 from XCode 9.2.

Moving issue/pr template to docs/. Added links in README.

This reverts commit 1b0e38d.

Fixes crash/assert bug introduced in d845135 (#1651): would assert when showing the CTRL+Tab list and or fallback "...." tooltip.

Viewport: Added ImGuiWindowClass / SetNextWindowClass() (concept imported from Docking ImGuiDockFamily), which currently allows to overwrite viewport flags on a per-window basis. Exposed FindViewportByID(). Win32: Support for ParentViewportId. (#1542)

Viewport: Win32: Workaround to the fact that ::WindowFromPoint() seems to return Windows using ImGuiViewportFlags_NoInputs / HTTRANSPARENT when dragging nearby the platform title bar. This is to allow using platform decoration. I don't understand this well atm. (#1542)
