According to the attached debug output OSX's CGDisplayScreenSize() reports that the particular 
monitor is huge (97cm x 68cm) and the device resolution is low. In order to maintain the current notion 
that a 100% zoom level should really mean that (e.g. a letter-sized page is supposed to be displayed as 
letter-sized page  on the screen too) fewer pixels are used.

This results in the problem that for screens with few pixels per page the text becomes unreasonably 
small. This scenario happens e.g. when displaying on large TVs or when a monitor misreports its 
extents as in the attached debug-session.

@requirements: I suggest to give up on the goal to have a 1:1 relation between the target paper size 
and the screen size for a zoom level of 100% when the assumed device resolution is too low. It just 
doesn't make sense to demand e.g. a default font size of 10 points when this results in a font height of 
two pixels.
