Version 1.64 WIP

Version 1.63

Internals: Tidying up, moving helpers to imgui_internal.h (in prevision of 1.64 refactor)

ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSL values would erroneously alter the resulting color. (#2050)

Internals: Merged some changes to facilitate 1D->2D transition for some elements, and merging the stack layout PR (#846)

Internals: Renaming of non-user facing parts from ValueChanged to Edited terminology. (#2034, #820, #956, #1875)

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)

Internals: Wired a ImGuiItemStatusFlags_ValueChanged into ItemStatusFlags, for an hypothetical IsItemValueChanged() function. (#2034)
