 Summary of the enhancement request:

 bitand (and bitor) operations function at 8 bit, I'd like to use bitand to
 work with the lower bits of some 10 and 16 bit video but it seems that
 bitand only finangles the first 8 bits.

 Here is a command I would use to solo the 8th bit of the Y plane. I would
 like to do similarly with lower bits.

 {{{
 bit=8
 ffplay 10bit_v210.mov -vf
 "extractplanes=y,lut=c0=bitand(val\,pow(2\,8-${bit}))*pow(2\,${bit})"
 }}}
