[cairo] cairo_append_path performance

Most graphics systems have the concept of a path as a first class object.
In cairo we expose a path structure but its not the same as the one
And you don't have access to many operations your would like to
perform on a path.
For example hit tests.
My solution is to use a cairo_t with a 1 pixel surface to represent a
path this gives
a nice api for paths except for one problem.
To copy this path to the real surface for rendering involves copying
it out into a cairo_path_t
then appending it to the real surface resulting in a path copy and a
for large paths.
Can a new public method be added to do the copy using the internal
structure removing this
extra allocation ?
