Operators

 * New Cleanup Frames operator.
 * New Step parameter for Interpolate Sequence.
 * The convert mesh to strokes and bake mesh animation, now create layers and materials using the original object name. Also fixed problems when convert or bake animation for several objects at the same time.
 * New material option to set as Holdout. This allows to open holes in filled areas. This option only works when the stroke uses Material mode.




 * New Trace Images operator using Potrace library.



This functionality is designed to trace a black and white image into grease pencil strokes. If the image is not B/W, the trace try to convert to bitone image. For better results, use manually converted to black and white images and try to keep the resolution of the image small. High resolutions could produce very dense strokes.
