Context: NewFrame() asserts (#1565)

Merge branch 'master' into navigation

Metrics: Removed context size display.

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

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)

Comments

Simplified return of ImGui::IsKeyReleased()

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)

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.

DragFloat: Fix/workaround for backends which do not preserve a valid mouse position when dragged out of bounds. (#1559)

Drag and Drop: Increased payload type string to 12 characters instead of 8.(#143)

NewFrame(): Added an assert to detect incorrect filling of the io.KeyMap[] array earlier. (#1555) + comments.

InputText: Cursor X position not lost when clicking outside on an item that's submitted after the InputText(). It was only noticeable when restoring focus programmatically. (#1418, #1554)

Nav: Fixed popup wrap-around logic for windows with scrolling. (#787)

Merge fix.

Internals: DrawData: We don't need an intermediate layer for popups.

Metrics: Tweaks to hover-window-drawlist to see window bounding box.

Internals: DrawData: Refactored chunks into a ImDrawDataBuilder we can reuse.
