Viewport: Fixed a viewport bug which led some popups to merge in underlying host viewport when they should be z-over their parent viewport.

Examples: DirectX10/11/12: Made imgui_impl_dx10/dx11/dx12.cpp link d3dcompiler.lib from the .cpp file to ease integration.

Version 1.67 WIP (again, this time IMGUI_VERSION_NUM has leeway for another hot-fix).

Version 1.66b (will revisit how to change IMGUI_VERSION_NUM across versions, this commit reduces the numerical IMGUI_VERSION_NUM compared to the commit on Nov 22).

Fixed a text rendering/clipping bug introduced in 1.66 (on 2018-10-12, commit ede3a3b9) that affect single ImDrawList::AddText() calls with single strings larger than 10k. Text/TextUnformatted() calls were not affected, but e.g. InputText() was.

Viewport: Fixed a bug where tooltips on their first frame didn't find a monitor leading to the "recovery" code to revert it to the main viewport for a frame. (#1542)

When the focused window become inactive don't restore focus to a window with the ImGuiWindowFlags_NoInputs flag. (#2213)

Docking: Comments + maiintain LastFrameFocused per node + using bitfiield for docking bools.

Docking: Added context menu option to hide the tab bar of single-window dock nodes, similar to Unreal. (#2109)
