BeginPopupContextItem(): Skip processing when SkipItems is set as LastItemId is unreliable and we assert when it is zero. + Minor comments on columns.

Fixed GCC mem-access warnings (#2565) ...

+ using "if defined" more consistently for Clang.

Docking: Fixed temporarily losing Dockspace flag when merging remaining sibling back into a parent node. (#2563, #2109) ...

Would trigger an assert in the Passthru hole path. Broken by fd5859ed.

Docking: Fixed undocking whole node (from collapse/docking menu button) from losing its size/pos. Made collapose/docking menu id easier to compute for testing.

Update changelog, comments, made empty/no-text clipboard return NULL as with other implementation. Minor style tweaks. (#2546) ...

Fixed IMGUI_DISABLE_WIN32_FUNCTIONS not disabling IME code.

Add native mac copy/paste support to match win32 (#2546)

Docking: Fixed incomplete merge of 36e714a leading to undocking. #2109

Fixed uses of IsItemDeactivated(), IsItemDeactivatedAfterEdit() on multi-components widgets and after EndGroup(). (#2550, #1875)

Internal: Renamed fields + minor tweaks (probably shallow break stack-layout pr, sorry!)

Internal: Removed GetNextItemWidth(), relying on ItemAdd or NextItemData.ClearFlags() to clear the width data. Amend 5078fa20 and undo some of its effects of imgui_widgets.cpp

Renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Refactored SetNextItemXXX stuff to match SetNextWindowXXX code closely.

Internal: Storing flags for NextWindowData so that we can clear everything with a single write and remove dummy condition fields.

Internal: Minor tidying/reordering of sections within ImGuiContext / window DC.

Tweak EndGroup() to facilitate fixing #2550 later (currently should have no side-effect0. Demo: Add extra widget to status query test.

Fixed unused variables warnings when asserts are compiled out. (#2551)

Cast ImTextureId to void* before printing in Metrics window. (#2548)

IO: changed AddInputCharacter(unsigned short c) signature to AddInputCharacter(unsigned int c). ...

Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(), the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode support. (#2538, #2541)

Fixed a PVS Studio static analyzer warning.
