cairo_status_t is used to indicate errors that can occur when
using Cairo. In some cases it is returned directly by functions.
but when using cairo_t, the last error, if any, is stored in
the context and can be retrieved with cairo_status().
New entries may be added in future versions. Use cairo_status_to_string()
to get a human-readable representation of an error message.
