Note to self: attempt to write a program to read BMax documentation and browse it easily.
Not being able to find what you're after is only half the issue. The other half is the info you'd expect to be in the docs just doesn't exist. I used the search function in the chm'd docs and couldn't find a thing on Tgraphics... which was quite baffling to a newb like me, since people were referring to it everywhere.
