This commit adds two separate modes for defining angular spacing between elements in the PD's Polar Pattern: 1. Overall Angle - which behaves exactly like it behaved before, 2. Offset Angle - which allows user to specify separation angle between consecutive elements. This change is analogue to that introduced for LinearPattern in previous commits.

|
|
*
|
|
* Depending on Mode selection list will be constructed differently:
|
|
* 1. For "angle" mode each feature will be rotated by (Angle / (Occurrences - 1)) so
|
|
* that the transformations will cover the total Angle. The only exception is Angle = 360 degrees in
|
|
* which case the transformation angle will be (Angle / Occurrences) so that the last transformed shape
|
|
* is not identical with the original shape.
|
|
* 2. For "offset" mode each feature will be rotated using exact angle from Offset parameter. It can
|
|
* potentially result in transformation that extends beyond full rotation or results in overlapping shapes.
|
|
* This situations are considered as potential user errors and should be solved by user.
|
|
*
|
|
* If Axis contains a feature and an edge name, then the transformation axis will be
|
|
* the given edge, which must be linear.
|
|
*
|
|
* If Reversed is true, the direction of rotation will be opposite.
