Subject: [PATCH 1/2] Draft: Fix Draft_PointArray and Draft_TwistedArray Count
 problems

Draft_PointArray and Draft_TwistedArray have Count problems:
1. Draft_PointArray: Count is always zero.
2. Draft_PathTwistedArray: Number of items is Count+1.
3. Draft_PathTwistedLinkArray: Count is increased whenever object is recomputed.

Also the first item in a twisted array should be unrotated.
