A simple DirectShow video renderer that renders HAP video (Hap1, Hap Alpha, Hap Q) as well as the corresponding raw DXT data types (DXT1, DXT5, DXTY).
For HAP AVIs it supports both videos rendered with the Renderheads VfW codec and with FFmpeg. If you use a splitter filter like LAV Splitter/LAV Splitter source filter also containers MOV and MKV can be used.
The renderer creates a window with OpenGL context (using GLFW 3.3), and displays the video in this window. The window is transparent, so HAP Alpha video will be rendered directly over the Windows desktop (TODO: add a property dialog and API that allows to switch to undecorated/chromeless window mode - at the moment the window always has a title bar and border).
The main purpose of this filter is to allow to explore and test HAP and DXT flavors in DirectShow editors like GraphEdit/GraphStudio/GraphStudioNext.
