// Check if a source is needed in a 3-way bitblt operation.
// This works on both rop and rop3. We assume that a rop contains zero
// in the high byte.
//
// This is tested by comparing the rop result bits with source (column A
// below) vs. those without source (column B). If the two cases are
// identical, then the effect of the rop does not depend on the source
// and we don't need a source device. Recall the rop construction from
// input (pattern, source, target --> result):
