1. Pinch scale and rotate now always act around object centre unless an anchorPoint (in the case of Bitmaps) has been set. This involved replacing all of the move/scale/rotate options with matrices.

2. Pinch and drag now work correctly when the object in question resides in a parent that has been translated/rotated/scaled itself.

3. Removed the dubious option to use "oldStyleHysteresis". Now all operations use this style and to avoid any hysteresis "jump" effect you have to reduce the hysteresis value. For this reason, all default hysteresis value are now zero so no jump will occur.

4. Added moving average smoothing to scaling and rotation to avoid jitter.

5. Because of the way that pinch dragging is now integral with the matrix calculations for rotate and scale, it is no longer possible for BhDrag to be used for two finger dragging at the same time as BhPinch is doing scale and rotation. Hence if you are using BhPinch you mustn't allow BhDrag to be active at the same time. See demo program for an example of how to use BhPinch and BhDrag together.
