AW: Can't pick the mousecolor with brush tool while mousedown

[Tiemo Hollmann TB]

Hallo Björnke,
good approach, I never would have thought about this. I am still struggeling
with the funny (but understandable) zebra effect, but perhaps I'll find a
way. I think I have to find a way to check if I am already outside of the
range of the pixels (size of the brush tool) I just have drawn, before I do
a new color comparison.
Thank you
Tiemo
