Cairo is an excellent library, and it's a great idea to bind it to Lua.
Thank you for sharing your extremely useful work!
There are some other useful libraries that plug together with Cairo,
that you might be interested in integrating with Lua:
Pango: text formatter, supporting unicode, internationalized text
layout, simple html-like markup formatting, that uses Cairo to handle
fonts and draw text.
poppler: PDF file reader and renderer with a Cairo back-end.
rsvg: SVG file reader and rederer with a Cairo back-end.
Firefox is developing a Cairo back-end for rendering dhtml, SVG, and
everything else, and will support rendering with 3d hardware
accelerators across different platforms!
GTK supports Cairo and Pango, and pygtk and pycairo expose them to
Python, so that other Python modules like pypango and your own rendering
modules can be passed a Cairo context and call Cairo directly, to render
very efficiently through the same Cairo context as the rest of the
system is using to draw. (The pycairo module installs some .h files that
your dependent module includes, that allow it to extract the cairo
context from a Python wrapper object created by pycairo.)
The OLPC (One Laptop Per Child) project is using Cairo and other related
libraries, and there's a lot of work going into improving an optimizing
Cairo is great for drawing scalable interactive user interfaces, as well
as video overlays, information visualization, maps, graphs and data
Here are some pictures of the pie menus I wrote in Python for the OLPC,
and drew with Cairo and Pango (and a link to the source code):
