doc: Fix many qdoc warnings, mostly missing return types

Fixed many cases of missing return types in \fn commands.
Added a fake GLxxx typedef for a GL type that wasn't there
because the GL includes weren't accessible. Also added some
fake declarations for a few functions declared in namespace
Qt in QtWidgets that must be seen by qdoc in QtCore.
