--- Comment #14 from Axel <arnolda747 at gmail.com> ---
An unpleasant follow-up: I just noticed that the June 24 patch for the MacPorts
kdelibs4 jeopardizes my patch. It makes rasterization the default rendering
method rather than using the native rendering which is retina-capable.

There are two ways to get the native rendering back, which are really
MacPorts-specific:
- either, one edits once more the Info.plist, and adds an environment variable
"RasterOff".
- or, one calls a static function of KApplication called doNotRaster before
creating the KApplication.

The latter approach definitely can't go into the main digikam source, since it
is MacPorts-specific, and only for versions of kdelibs4 >= 4.12.5_1. Setting
the environment variable won't harm, but looks a bit ad-hoc for those that
compile kde themselves. It also can't be fixed in MacPorts at the moment, since
MacPorts installs still digikam 3.5.0.
