Revision 7c55263f

Added by Leszek Koltunski almost 4 years ago

Library: introduce a new form of the MeshRectangular grid, where the individual rows and columns can be each of different width. This help reduce the number of vertices in objects as typically we are only interested at distorting a certain subregion.

Modify the Bean app to take advantage of this.
