This is a revert of 6c0181c. Testing showed that we got a big
performance hit by enabling this, and we also saw some graphical
artifacts. More work is needed before this can be enabled by default.
MacOS package: Added NSHighResolutionCapable tag to Info.plist
With the flag the application will start enable the high resolution
display. I tested this on a Macbook Pro with a High Resolution Display.
The fonts are better to read.
