Performs an edge detect using Sobel filter.

The result is a gray scale bitmap: high values (closed to 255) are edges.

When ImageLocation is Drawable, the output pixel format is RGB 24, otherwise it is gray scale 8 bit.

To make result black/white (with 1=edge) it is suggested to call ConvertToBlackWhite(Threshold,-2), that uses Maximum Entropy Algorithm.
