ProPainter Vapoursynth filter

[Dan64]

I debugged the source and it seems that sometimes (depending on the input mask) the call to the function:

scipy.ndimage.binary_dilation(mask_img, iterations=mask_dilates)

 provides a wrong dilated mask. Not clear why and the debugging of "scipy" function is outside my scope.

So in summary if you get wrong results try to set 

mask_dilation=0       # skip the call to scipy.ndimage.binary_dilation()

   
 and check if this solve the problem.

P.S.
If you provide as input a low resolution mask, the mask is resized to the frame dimension inside the filter. 
In my tests mask_dilation=0 fixed the issue, but I worked on a small size clip.
For sure there is a problem on mask handling, probably due to memory constrains and using a mask region is the optimal way to manage it because the inference is performed only on the clip having the size of mask region.
