If you name the meshes `fsaverage/surf/lh.whatever` and `rh.whatever`, you
might be able to use `surf='whatever'` in PySurfer. Not sure if we sanity
check the names, or just check to see if the files exist, but it's worth a
shot.

They need to preserve the vertex ordering, otherwise plotting will not
work. I would first check to see if there are the same number of vertices,
if they are, then try plotting some data on the builtin meshes, then on
yours.
