Note that we have added the ability for gmsh to render post processing 
result based on a mesh.
Files will be much smaller, of course.
We have not (yet) done any documentation but all that is in the code. At 
this point, we
have not 'yet) decided which input/output format we will choose. Vtk is 
a candidate.

We have chosen NOT to do that several years ago. The reason is pretty 
simple : without any
third party software, gmsh's executable size is about 2 MB. When adding 
vtk, it grows to
15 MB. We think this is not acceptable.
