Michael Fabian 'Xaymar' Dirks bc63696306 gs-mipmapper: Early attempts at proper mipmap rendering 
This class is an attempt at adding dynamic mipmapping support to OBS, which is lacking this feature. It is pretty much a hack until I figure out how to do it for both d3d11 and opengl and can make a PR for obs-studio to include this ability by default.
