Well I'd like to explode it.
This is what I have so far:

Comments?
One thing that I would like to be able to show is, when you have one line
going into a box and two lines coming from it, is a branch occuring or is
it an either or situation. ie a choice is made and only one path is taken.
I've attached the latest WIP of control_flow.png to help show this.
RM = Resource Management
or = 1 of these 2 paths are followed
& = both of these 2 paths are followed
2D = 2D commands & data
3D = 3D commands & data
lines in columns indicate individual paths while,
lines not in columns are agregations of paths.
eg's in my bit of exploded ascii art and the X Server.
This becomes somewhat of an issue when you have multiple line entering
and leaving a box, so if the lines should match up and don't or vice
versa - let me know.
DRMLib whats the differnce between the one in the X Server and the one in the 3DDRP?
They both talk to Kernel & SAREA (SHM & IOCTL).
