I'd rather suggest introducing some conversion functions between
relative and absolute coordinate systems. Newer versions of Mac OS X
provides "Resolution Independence" that allows users to specify a
scale factor:
http://developer.apple.com/mac/library/documentation/UserExperience/Conceptual/HiDPIOverview/HiDPIConcepts/HiDPIConcepts.html
With the scale factor, 1 pixel in the relative coordinate system no
longer always correspond to 1 pixel in the absolute one. Thus one
cannot determine the corresponding absolute coordinates only from
`inside-left' and `inside-top'.
