*
* This file is written with the intention of being easily converted into a
* class capable of throwing exceptions if data is out of range.
*
* If an operation fails, subsequent operations will also fail. The sizebuf
* is assumed to be in an invalid state. This COULD be changed pretty easily
* and in normal Quake IIRC it is. But our MO is to bail on failure, not
* figure out what went wrong (making throws perfect).
