[VB6] Wheel Color Picker

[Eduardo-]

thanks for improvements and fix errors.
better I can think of is using the mouse wheel to control the slider you would have better accuracy but is not very relevant.
greetings and good work

Updated.

I added the mouse wheel support, for the slider and for the wheel.
I had to add subclassing code for doing that.
To have "accuracy" you need to hold the Shift key pressed while scrolling with the mouse wheel.
