Thanks for the quick response.  I'd like to try your patch, but so far I 
have not succeeded in building cairo-java from CVS.  I get this error 
when I execute 'make':

/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/../../../../i686-pc-linux-gnu/bin/ld: 
cannot find -lglibjava
collect2: ld returned 1 exit status
make[1]: *** [libcairojava.la] Error 1
make[1]: Leaving directory `/home/dgilbert/cairo-java-cvs/cairo-java'
make: *** [all] Error 2

I know nothing about this stuff, I only got cairo-java working via the 
Gentoo ebuild.  Any hints?

Dave Gilbert

P.S.  By the way, my interest in cairo-java is to create a 
CairoGraphics2D class that can be used with JFreeChart (and any other 
applications that use the Graphics2D API).  I started that and got some 
promising results before running into the getMatrix() problem.  Here are 
some PNG images I created with a very basic Graphics2D implementation 
(I'm sure it can be improved a lot):

This is running on Sun's JDK but I'm hopeful of getting the same thing 
running on JamVM and GNU Classpath.
