Viewport: Fix viewport regression with protruding child window creating their own viewport. (fixes cae4d02, 760c1d95) (#1542)

Docking: Added ImGuiConfigFlags_DockingNoSplit flag. (#2109)

Viewport: Added support for minimized window which caused problem when ImGuiBackendFlags_HasMouseHoveredViewport was not supported. (#1542) + todo

Viewport: Avoid unnecessary reapplying platform pos/size every frame. (#2205) + Fix GLFW ImGui_ImplGlfw_CreateWindow() from not applying position immediately. Clear LastNameHash properly (bug already fixed in Docking branch)

Viewport: Merging/Extracting to/from main host viewport is now performed based on current state rather than triggers. Windows which don't fit in host window are now consistently in their own viewport. Toward simplifying the UpdateSelectWindowViewport() function. Probably broke something.. (#1542)

Viewport: UpdateTryMergeWindowIntoHostViewport() calls BringWindowToDisplayFront() - possible now that BringWindowToFocusFront() is a different function.

Version 1.67 WIP

Viewport: Stop relying on viewport->CreatedPlatformWindow to create Platform_DestroyWindow and Renderer_DestroyWindow. Explicitly require Platform_GetWindowFocus() to require supporting empty data.

Version 1.66

Nav: Fixed explicit directional input not re-highlighting current nav item if there is a single item in the window and highlight has been previously disabled by the mouse. (#787)

Internals: Using GetOverlayDrawList(ImGuiWindow*) to match syntax of viewport/master branches. Fixed compiling with IMGUI_DEBUG_NAV_RECTS

Removed unnecessary ImGui:: prefixes.

Internals: Added FindWindowByID() helper. (#2190)

Nav: Fixed an assert in certain circumstance (mostly when using popups) when mouse positions stop being valid. (#2168) + adding a else block to make NavCalcPreferredRefPos() more explicit.

Viewport: BeginMainMenuBar(): explicitly set viewport to avoid creating new one when ImGuiConfigFlags_ViewportsNoMerge is set + misc shallow changes.

Docking: Fixed a regression where clicking a Tab wouldn't immediately set NavWindow. Which led to breaking the NavSaveLastChildNavWindow/NavRestoreLastChildNavWindow logic. (#2109)

Made IsWindowFocused() work outside of NewFrame()-EndFrame() and added comments about how ImGuiFocusedFlags_AnyWindow should NOT be used in place of io.WantCaptureMouse. (#2185)

Viewport: Fixed SDL+OpenGL2 example to work with multi-viewports. (#2175)

Config: Added IMGUI_DISABLE_WIN32_FUNCTIONS to disable linking with _any_ Win32 function, as a general forward compatible measure.

Doc: Fixed comments referring to LoadFromFileTTF() instead of AddFontFromFileTTF() (#2153)
