...I'm actually concerned that I went a bit overkill trying to prevent backwards compatibility issues with this abstraction design, because this is a large number of files that have to be modified just to add a single graphics subsystem export. Someone's going to strangle me, and when you know that someone might strangle you, that means that you did something wrong. We'll have to look in to simplifying this in the future without killing backward compatibility safety.
