Great !

The coding style seems similar to the one I was thinking of using. With the 
exception of the capitalization in first letter of the methods (but that's 
only small details).

By the way, another thing that I tough of was the possibility to have 
automatic status checks (after any operation that might fail) and react to 
that failure by (optionaly) throwing an exception.
I think this is a good idea, but as I don't have too much experience using 
cairo i'm still unsure. It's certainly a better way of checking for error 
conditions, but cairo seems to be able to keep going even if certain errors 
occurs (say, cairo_create() is called when cairo_status()==
CAIRO_STATUS_NO_MEMORY).
This could eventualy be made in a way it was possible to disable the checks 
with a #define or with a simple bool in the wrapper class.
What do you think of this ?

If you need any help, just ask.
Cheers,

Rui Pires.
