it's also possible to create an object that's using bitwise AND operations:
such as:
inlet |______________________.. | | .. & N1 & N2 .. | | .. == N1 == N2 .. | | .. outlet outlet
with Nx=1,2,4,8,16,32,64...
it should work similar to pix abstraction, but i suppose that's cheaper ;-)
and it's easyer if you are only looking for a single bit...
btw, why isn't it allowed to create an expr like: expr ( ( $f1 & (2^$f2) ) == 2^$f2)
