I am sorry -- I assumed since this reached the top page of HN that this was a bit more serious that just some dude's personal project. This portable graphics API thing has been tried 10000x and they are almost never useful for any significant app you want to write. I see one of these and I hope that maybe someone has figured it out -- one glance and I see no documentation nor any rational as to why this effort is unique, then I know this is not a serious offering.
