Certainly better than _YT / _YB.

That's no argument.  First, it does not have to make a difference (the code 
can simply take min/max), second: you have to know anyhow that 0,0 is top 
left, otherwise the user would swap TOP/BOTTOM coordinates (and in that case 
taking min/max would be a conceptual hack IMO).
