GlyphDescription
public class GlyfCompositeDescript extends GlyfDescript
Glyph description for composite glyphs. Composite glyphs are made up of one or more simple glyphs, usually with some sort of transformation applied to each. This class is based on code from Apache Batik a subproject of Apache XMLGraphics. see http://xmlgraphics.apache.org/batik/ for further details.
