There are VM changes needed.
In the way the current Cog VMs are built by Eliot,
it is impossible to support the retina resolution 
(because it uses the Carbon way of doing things).
  The so-called “iOS VMs” (ie, the iOS folder of
the platform dependent VM files/plugins) are
Cocoa based and can be used for either OS X or
iOS. There it would be possible. I already tried
but it was complicated and I got distracted.
AFAIK the way the Pharo folks build the VM
(ie, https://github.com/pharo-project/pharo-vm/)
can be used to generate a Coca-based Cog VM.
