use QScreen unconditionally instead of libkscreen
Review Request #126913 - Created Jan. 28, 2016 and submitted
This patch removes libkscreen usage and ports it to QScreen.- Instead of retrieving and polishing the DPI from libkscreen, use the widget's windowhandle to retrieve the current screen and return that as the widget's DPI. - Remove libkscreen from buildsystem - Kill old libkscreen code. This wasn't built anyway, and wouldn't build against new libkscreen anyway.
little, started okular on my laptop and viewed a pdf, nothing odd going on...
