Revision 7437ebb3

Added by Leszek Koltunski almost 5 years ago

Still a fix for the previous fix - cubits lie on faces only if their RotationRow is very close to 0 or mSize-1, and not when their RotationRow rounded to the nearest integer is 0 or mSize-1 ! ( counterexample: the rotated tetrahedrons of Pyraminx )
