Hello,
i'd like to mark code, located in Bitblt>>copyBits as buggy,
regardless that it's currently working.
A simple reason: if there is no such primitive, or primitive
constantly fails, then code, located in method's body leading to
infinite recursion.
I consider this as a major bug, especially in such critical place,
where correct behavior is at utmost importance.

A simple replacement of #copyBits to #copyBitsAgain in method should
prevent further recursion caused by primitive failure.
