I've sent them to Greg Haerr and a couple other people, and a few of the
modifications have made their way back to the trunk, but there's a still
quite a lot of outstanding code to merge.  a co-worker literally rewrote
the guts of the line draw routines, and that's where a lot of merge
conflicts occurr.

0.90 is the last official release, and there has been work done on the
CVS branch since then.  actually that may be a path for me to do the
merge; the last time I spent any in-depth effort to merge was against a
CVS version, not 0.90...
