.. Ugh
I need Font::renderText() to be const, because I'm passing constant references of Font objects in certain functions that use this function. Theoretically, a renderText() function that renders to a extranous surface and returns that should be totaly okay with being const. I don't quite understand what I'm doing wrong.
