CollapsingHeader(bool*) variant: fixed for IsItemHovered() to work properly in the nav branch.Basically the close button now has to use ItemAdd() to be navable into, which overwrite the IsItemHovered data. (#600, #787)

Internals: ButtonBehavior: made ImGuiButtonFlags_PressedOnClick and ImGuiButtonFlags_PressedOnDoubleClick set the click offset correctly + hold on g.ActiveId so Held state can be reported. Added ImGuiButtonFlags_NoHoldingActiveId flag to disable the later.

Checkbox: Using checkmark. MenuItem: Tweaked checkmark, thicker.

Begin: Marked 5 parameters version of Begin() as obsolete. Now waiting for a riot to happen!

Begin: Work toward obsoleting the 5-arguments Begin() overload. Internal BeginEx() becomes the normal public Begin() again! (4)

Begin: Work toward obsoleting the 5-arguments Begin() overload. Removed bg_alpha from internal BeginEx(). (3)

Begin: Work toward obsoleting the 5-arguments Begin() overload. Removed size_on_first_use from internal BeginEx(). (2)

Begin: Work toward obsoleting the 5-arguments Begin() overload. (1)

BeginPopupContextItem() now supports a NULL string identifier and uses the last item ID if available. For interactive items (that have an ID) this works! For non interactive items we assert.

Fix IsItemHovered() issue on child by temporarily reverting 344d48b. This is not the ideal solution. (Fix #1370)

Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787)

Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787)

Nav: InputText: Fixed using Up/Down history callback feature when Nav is enabled (#787)

Nav: Internals: Moved some internal code to namespace, comments

Nav: NavProcessItem() updates current NavLayer. Basically we're hearing toward rebuilidng nav info from an id. (#787).

Nav: NavProcessItem() computes window-relative rectangle using own Window rather than NavWindow. Not sure what it may mean for child-flattened-nav (disabled). (#787)

Nav: SetFocusID() update NavWindow and NavRectRel just as we get them. Needed by upcoming commit, committing separately as I'm curious if it has any side-effect. (#787)

Merge branch 'master' into navigation

Nav: Renaming a field + Comments.

Removed apparently unncessary code in InputFloatN() and InputInt().

Nav: ButtonBehavior() keep _displaying_ NavId item as howered when refocusing or moving window, which is consistent with IsItemHovered() and reduce noise/flicker (#787)

Reluctantly exposed GetActiveID(), GetHoveredID() in imgui_internal because the demo code will need it.

Nav: Shallow tweaks.

Exposed Scrollbar() in imgui_internal.h and removed a bool arg

Nav: Internals: Renamed ImGuiButtonFlags_NoNavOverride to ImGuiButtonFlags_NoNavFocus + fixed a theorically missing test in ButtonBehavior() (#787)

Nav: Internals: Renamed SetActiveIDNoNav -> SetActiveID() and old SetActiveID() -> SetFocusID(), both functions needs to be called when both are desirabled. (#787) ...

May break code relying on imgui_internal.h, relying on nav and not calling ButtonBehavior().

Internals: Moved SetNavID() and renamed casing to be consistent with stuff exposed in imgui_internal.h
