-----------------------------------------------------------------------
VERSION 1.79 WIP (In Progress)
-----------------------------------------------------------------------
Other Changes:
- InputText: Added selection helpers in ImGuiInputTextCallbackData().
- InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit.
(note that InputText() already returns true on edit, the callback is useful mainly to manipulate the
underlying buffer while focus is active).
- DragFloat, DragScalar: Fixed ImGuiSliderFlags_ClampOnInput not being honored in the special case
where v_min == v_max. (#3361)
- BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(),
so e.g. calling the function at the end of a window would often add +ItemSpacing.y to scrolling range.
- TreeNode, CollapsingHeader: Made clicking on arrow toggle toggle the open state on the Mouse Down event
rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior
and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.
(This is also necessary to support full multi/range-select/drag and drop operations.)
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
- Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
