Maya tesselation support

[calus]

We should have the option in the plugin UI to use Maya tesselation,

Furthermore this would give us out of the box support for every Maya geometry (nurbs, smooth mesh preview, concave n-gon, ...).

Please add a per shape option to enable the use of Maya tesselation.
This would give a workaround for many flaws of the plugin.
For example if Sudiv Crease is never supported in the plugin,
at least we could use Maya tesselation to get around that defect.
