Update of /cvs/cairo/rcairo/tests
In directory pdx:/tmp/cvs-serv31046/tests
Added Files:
spline test-nox text
Log Message:
Initial import of Ruby/Cairo.
I just moved the code around a bit in anticipation of wanting to do it later,
and I haven't tested if it broke anything yet, so don't be surprised if it
doesn't quite build yet.
