[cgma-dev] iGeom::reflectEnt signature

[Jane Hu]

Hi, Paul:

This change is due to cubit change from 12.2 to 13.1. Before it was assumed
to reflect against a plane crossing origin, and now it allows to reflect
any plane crossing any given point with any given plane direction.

You just need to give the point as (0,0,0) to let the previous passed tests
to run against cgm13.1 and above.

Hope it helps.

Jane
