Here's a list of changes since the last post:
- MUCH faster image updates. I've added a couple of functions to Blender that gives me a more direct route to the pixel data. This allows for 15-20x (guesstimated) faster updates. It can now play back filled in animated masks at an acceptable speed.
- Feathering!!! I finally managed to get it to work. There are some issues with large feather distances and sharp corners but since it is intended to be used to match the soft-edge of an in focus image element it is already useable. For bigger blurs you can attach a blur node to the mask's image node.
- The feather distance can be adjusted per point. The feather distance for every curve point between two points is calculated using the logistic function mentioned here. This gives it a nice sigmoid slope.
- Every mask now has a corresponding node in the Node editor. These nodes are fully managed (created/removed/updated) by Roto2D. The nodes can be forced to update by enabling 'Update nodes' in the panel.
- The masks now match the render settings instead of the image size. A dotted line shows the size of the mask in the editor.
- Inverting a mask. Just as fast as a non-inverted mask thanks to the new pixel functions mentioned above.
- Changing the Bézier resolution per mask. range: 10-80
- Translate, rotate & scale a mask or the selected points. Uses the standard Blender 'g', 'r' & 's' keys.

Most of the desired functionality is there. Now it's a matter of fixing a couple (Fingers crossed, knock on wood, etc.) of bugs and releasing it.
