* Added a new option to only calculate a certain number of frames before/after the current frame instead of defining a frame range. This is useful in certain cases on longer timelines, to be able to view the paths for certain regions quicker.
* When inserting a keyframe, if a bone already has path drawing on, the path for that bone will get automatically recalculated. More testing is required to see if there are any more cases where this would be useful. Also, a global setting to turn this on/off would be a good idea.
Todo (requested but not yet implemented):
* Parts of path before/after current frame could get drawn with different colours
