Either.  If the application is sure to be linked against a new enough 
Mesa that's known to have that function, it could be called directly. 
(I think many/most OSMesa users use the interface in well-controlled 
environments).  Otherwise, GetProcAddress would be safer.

Feel free to post a patch to add it to the exports list.

Thanks.
