[cairo] The short road left to 1.6 - EXTEND_PAD

[Antoine Azar]

Thanks for the very thorough code review Bertram. My comments inline.

I've had trouble with Visual Studio, hopefully everything should be fine now.

I integrated these changes, let me know if there's still any trouble.

I might be missing something but I don't see the usefulness of having 
a trailing semicolon. Is the comment only there to let developers 
know they should NOT append a semicolon to the define? if so that 
should probably be in the coding guidelines rather than in the code. 
Anyhow I put it back for now.

Done.

Done.

Good eyes! Fixed.

Here's the updated patch.
Thanks,
