#21 Cannot use the full resolution of a MBP Retina display

[geminga]

Defining a geometry of 2880x1800 should map the full resolution of the screen of a macboookpro 15" retina. Unfortunately chicken only use a lower resolution and i can only get a viewport of 1920x1200 maximum in full screen mode

Lack of HiDPI support makes Chicken unusable on my Macbook Pro 13" Retina :
Remote screens appear way too big, a remote 1500x960 screen is unusable !
A simple flag "use HiDPI (on/off)" would probably solve the problem, like Virtualbox offers in its VM settigs.
