And what about the re-entrancy issues of returning a pointer to static
data? The C library suffers greatly from this in a number of APIs.
Passing in a pointer to thread-specific data makes this all much

I have a strange though here -- we could mark the cairo calls which do
not change the state of the library by annotating the cairo_t* with
'const'. Would this be a good idea? Or would it only clutter the
headers? I'm not certain myself, but wanted to increase list traffic
with side discussions.
