So initial testing seems to show that the x/y positions of the second
monitor need scaling as well, but I didnʼt get around to testing all
the scaling/relative positioning combinations. Since thatʼs a less
common use case, we can apply your patch in the meantime. Do you have
an Emacs copyright assignment on file? If not, Eli, is the patch small
enough to apply without an assignment?

Thanks

Robert
