Image functions

Hi.

Here's a class with quite a few different functions to manipulate with images.

No credit to me, though. Christian Graus is the real author of these functions. I only ported it to VB.
I have re-written a few to take advantage of the ColorMatrix, but the hardcore functions like Swirl and Sphere and Water etc. are left intact.

The code is not commented, because I frankly have no idea what he's doing:blush:. I just changed to code and kept his formulas. :bigyello:

Have fun... :wave:

Updated version.

I finally figured out how to read and write directly to the memory, speeding the functions up by up to 10 times.
Some functions are twice as fast, but most are 3-5 times as fast.
