[Gmsh] About 2D algorithm.

[Cécile Giorla]

Hello,
In the version 1.65.0 of GMSH, we had 3 choices for the 2D mesh 
algorithm : isotropic, anisotropic and triangles.
 From the 2.0.0 version, we only can choose between MeshAdapt and 
Delaunay. What are the differences? Has the isotropic algorithm 
disappeared? Or only changed his name?
Is it possible to re-include it in the next version of GMSH?
Thank you.
Cecile Giorla.
