The Spherize filter is nothing new to Broomhead, it's been around in very early versions of Dogwaffle, but it's been significantly improved in this release.
 
Size: You can now set the size of the sphere, so it doesn't have to touch the edge of the image anymore or get cropped by a pixel.

Bump texture:  additional options were added to the menu for chosing the type of bump map or noise effects.
