I am testing it right now, starting by playing the demos and tests, of 
course.
They work fine, I think I will have some fun soon...

BUT (there is often a but, no?) two demos fail after spitting out a 
number of files:

C:\PrgCmdLine\luacairo
> lua5.1.exe draw.c.lua
lua5.1.exe: draw.c.lua:297: bad argument #2 to 'font_extents' 
(cairo.FontExtents.mt expected, got table)
stack traceback:
        [C]: in function 'font_extents'
        draw.c.lua:297: in function 'draw_textextents'
        draw.c.lua:402: in function 'draw_diagram'
        draw.c.lua:440: in function 'diagram'
        draw.c.lua:466: in function 'main'
        draw.c.lua:472: in main chunk
        [C]: ?

C:\PrgCmdLine\luacairo
> lua5.1.exe diagram.c.lua
lua5.1.exe: diagram.c.lua:420: bad argument #1 to 'matrix_init' 
(cairo.Matrix.mt expected, got table)
stack traceback:
        [C]: in function 'matrix_init'
        diagram.c.lua:420: in function 'diagram'
        diagram.c.lua:478: in function 'main'
        diagram.c.lua:504: in main chunk
        [C]: ?

Running on WinXP Pro SP2.

Good work, anyway!

PS.: don't search specifically, I did it and didn't find a clear answer. 
But if you know a way to make animated Gifs with Cairo, I would be glad.
Otherwise, I suppose I will generate a bunch of files and some tool to 
assemble them in Gif format.

Too bad MNG never took off.
