Title: Fixes for aspect ratio, new pixelate position filter and vignette filter enhancements

Updated Swirl and Bulge and Pinch filters to be correct for aspect ratio
Vignette filter has center and color parameters
Added new filter PixellatePosition for blotting out logos or faces
Added synchronous version of processImage in case you want to immediately generate a full image right after (i.e. changing the force output param to full size, calling processImage and then saving the image)
