Sources were rendering with a black border around them if they had a soft fade, which is due to how the shadow calculated the image sample. With the new shader code this is now fixed and the source looks like it should be. Additionally this removes the bug where enabling any shadow would cause only the texels to draw that were above the threshold. Additionally this adds support for inverse gradients (min > max) and negative gradients for outer shadows instead of only positive gradients. This technically allows for cleaner shadows.
