A photoshop-like BEVEL EFFECT in VB

This program takes a bitmap image and applies a bevel effect to it, adding hilights and shadows to make it appear 3-D. The direction and elevation of the light can be changed, as can the size of the bevel. Includes a "debug" mode which shows the process step-by-step (see screenshot) Some of the calculations have been converted to integer calculations for speed. Others still use floating-point, this is one future optimization that I might do.
