[Gtkradiant] Re: xml?

[Joseph, William]

I'm experimenting with loading code for files using the format below - to
see if the <primitive type="bleh"> <surf> arrangement is actually any better
than using <brush> <plane> and <patch> <matrix>. One reason i like the
abstract primitive/surf idea is demonstrated below with a "polymesh"
primitive using the same format. My hope is that i can use a standard set of
functions to convert the xml tree data into the format desired by each
primitive, instead of some custom-made specific functions for each
primitive. This should make things generally more extensible in theory..
