Added SetNextWindowBgAlpha() helper. (#1567) particularly helpul with the marking of the old 5-parameters version of Begin() as obsolete.

Comments + added legacy renamed GetItemsLineHeightWithSpacing() as stated in the doc, fixes 6190ab0

Nav: Comments, tweaks

Internals: Exposed SetCurrentFont() in imgui_internal.h

Style: Exposed ImGuiStyleVar_WindowTitleAlign, ImGuiStyleVar_ScrollbarSize, ImGuiStyleVar_ScrollbarRounding, ImGuiStyleVar_GrabRounding + added an assert to reduce accidental breakage. (#1181)

Internals: Moved unnecessary MovingWindowMoveId field.

Tweaked FAQ.

Context: NewFrame() asserts (#1565)

Examples: Made the Win32 proc handlers not assert if there is no active context yet, to be more flexible with creation order. (#1565)

Merge branch 'master' into navigation

Metrics: Removed context size display.

Examples: Updated for reorganized context functions. Calling CreateContext(), DestroyContext() in example code. Removed Shutdown() from binding code. (#1565, #586, #992, #1007, #1558)

Reorganized context handling to be more explicit, ...

- YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
- removed Shutdown() function, as DestroyContext() serve this purpose.
- you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwhise CreateContext() will create its own font atlas instance.
- removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
- removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts
(#1565, #586, #992, #1007, #1558)

Context: Renamed SetMemoryAllocators() to SetAllocatorFunctions(). Tweaked comments. (#1565, #586, #992, #1007, #1558)

Context: Added IMGUI_DISABLE_DEFAULT_ALLOCATORS to disable linking with malloc/free. (#1565, #586, #992, #1007, #1558)

Context: Removed allocator parameters from CreateContext(), they are now setup with SetMemoryAllocators() and shared by all contexts. (#1565, #586, #992, #1007, #1558)

Simplified return of ImGui::IsKeyReleased().

Simplified return of ImGui::IsKeyReleased()

ImFontAtlas: Added TexUvScale (= 1.0f / (float)TexWidth, 1.0f / (float)TexHeight)

ImFontAtlas: Moved mouse cursor data out of ImGuiContext, fix drawing them with multiple context. Also remove the last remaining undesirable dependency on GImGui in imgui_draw.cpp, finishing the work recently done with ImDrawListSharedData. Hurra! (#939)

Examples: Simplified mouse wheel handling. (#1463)

Examples: Allegro, Apple, DirectX9/10/11, Glfw+Vulkan :Added support for horizontal mouse wheel. (#1463)

Horizontal mouse wheel: renamed io.MouseHorizWheel to io.MouseWheelH. Reorganized the code in NewFrame(). Examples: Updated GLFW+GL and SDL+GL accordingly. (#1463)

Basic undocumented/unsupported combination of Child+Tooltip. The full feature needs substancially more work but this is enough for simplest cases. (#1345)

Begin: Removed asserts that got in the way of some flags combination. (#1345)

MovingWindow: Track click offset based on root window (undo 514d30d). This should not affect the patch used for #1345 as the RootWindow for Child+Tooltip window points to itself now.
