ImVector: Made a struct. Using T/T* in the code instead of value_type/iterator. Renamed index_from_pointer() to index_from_ptr() (was not documented, added in 1.63, users not supposed to use ImVector, hopefully not a big deal).

Minot internal tweaks, comments

Tests: Reworking hook prototypes for imgui-test to be faster and multi-context friendly.

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.

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

Tweak changelog + tweak internal render helper functions.

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.

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.

Docking: Fixed a bug undocking a window from its tab when it is the only docked window of a root dockspace with ConfigDockingTabBarOnSingleWindows enabled.
