Extend abcm2ps to support direct generation of PNG, SVG and PDF files
...The Cairo graphics library is an open-source graphics library
offering a similar 2D graphics model to PostScript. The Cairo
library can write to a GTK canvas, allowing integration with programs
using the GTK+ toolkit, or it can write to an image file in a choice of
formats: PNG, SVG or PDF.
This means that other programs can have access to the abcm2ps
music-rendering capability without having to incorporate a
PostScript interpreter.
