screen_capture_lite turned out to be pretty broken and so I brought back my old X11 implementation for the Window node, for Unices only. Hopefully SCL actually works on Windows because lemme tell you, I do not want to go knee-deep in that. Additionally, SAIL was replaced with stb_image because I couldn't get SAIL to build under MinGW.
