Utility to get the opengl texture associated with a x11 window.
It is recommended to use this over https://git.dec05eba.com/window-texture/about/ since EGL window textures are more reliable than GLX window texture, especially on nvidia. For example when you use a compositor such as picom you cant get window textures on nvidia (only one application gets access to window textures at a time). However with EGL there is no such issue (limitation) on nvidia (nor amd and intel).

Dependencies

egl (a library such as libglvnd), x11, xcomposite
