rule 41 code in the BitBltPlugin
is not mine. :)
I just took an effort to integrate already existing work made by other(s).
I had to change the methods in order to replace _ with := for
assignments and also use annotations <..foo.. > instead of 'self
that's why those methods stamped by my name.
But i didn't changed any semantics, just made sure it works.
