What is Opal?

Opal is a drawing library similar to Quartz 2D. Opal is built on top of Cairo (currently it is mostly a thin wrapper on top of the Cairo API).

Opal is also a gemstone consisting of amorphous hydrated silicon dioxide (SiO2 · nH2O) which is sometimes included in the quartz group of minerals.

The sources are available from the GNUstep repository at 

svn://svn.gna.org/svn/gnustep/libs/opal/trunk
