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.
This includes `array`, `base`, `bezcurve`, `block`, `bspline`,
`circle`, `clone`, `dimension`, `draft_annotation`, `draftlink`,
`drawingview`, `ellipse`, `facebinder`, `fillet`, `label`,
`patharray`, `point`, `pointarray`, `polygon`, `rectangle`,
`shape2dview`, `shapestring`, `text`, `wire`, `wwproxy`.
These are added to the `draftobjects` Doxygen group
so that the functions and classes contained in each module
are listed appropriately in the automatically generated
documentation.
This class was created by realthunder during the `LinkMerge`,
in de66e563e0, to demonstrate how to use the `App::Link`
objects to create Link aware arrays.
It is used by `draftobject.array` (ortho, polar, circular)
and `draftobject.patharray` to create respective Link arrays.
This class is a bit mysterious. We need more documentation
on how the properties are being set, and how the code interacts
with the arrays that use it.
