I think now you understand it is a bad idea to align high-DPI geometry
management of Emacs (or any applications) on OS X to those on other
platforms.

My patch provides a solution to some OS X-specific problem rather than
giving some OS X-only benefit which has some counterpart on free
platforms: the problem does not exist in the first place on other
platforms where high-DPI just means having many pixels without making
a physical monitor bigger (correct me if I'm wrong).  I believe
preview-latex users on other platforms are content with the current
output quality.

Hi-DPI model on OS X provides more aspects so it won't change overall
appearance in size on multiple environments that can change
dynamically, and such aspects are arguably specific to OS X GUI
framework.  Some GUI toolkits on free platforms may adopt similar idea
in some future, but Emacs on free platforms would not benefit from
them anytime soon because its geometry management relies on Xlib.
