MODE=0-31

This parameter and menu item indicate how the Morphing algorithm should search to find the points to use for morphing.

The values are additive:

   1 : Leaves un-triangled point stationary
   2 : Searches all the closest points
   4 : Uses a squaring algorithm to find close points
   8 : Uses a Delaunay algorithm to find triangles
   16: Precalculate close points

Default value is 0.
