Description:

libnxplot is a 2D vector drawing library, splitted from gNumexp (a graphical
frontend of NumExp). It has an API very similar to libplot, from GNU plotting
utilities. There are implementations, or drivers:

- nxplot-artft: this is a nxplot driver that uses libart_lgpl and
freetype to render a pixel buffer. The pixel buffer can be either associated
to a widget (a GtkDrawingArea, usually), or it can be created without widget
with an explicit size and later retrieved as a GdkPixbuf.

- nxplot-gp: this is a libgnomeprint based driver, to enable you to send
2D vector drawings directly to a printer without rasterization, thus preserving
all quality.
