well, but probably the generic solution would be better for this, as we
could just use _any_ array and upload it as EdgeFlag (whatever that is)
so we would only need (say) 4 arrays to cover everything.

might be good too; probably it would be ok to have several arrays of
different types (e.g. width-3, or uchar) and than let the user choose
which one is which.
