  (Viewport Branch)
+ - 2018/XX/XX (1.XX) - examples: the examples imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.)
+                       when adopting new bindings follow the code in examples/ to know which functions to call.

                         - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore. 
                           you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos)
