Blazingly fast™ & Easy to use Windows Overlay library

Asdf Overlay provides an easy to use interface to draw on top of window framebuffer by hooking rendering backends

GPU shared texture was used to avoid framebuffer copy via CPU. As a result, Asdf Overlay is capable of rendering overlay with any size without performance loss.
