Subject: Use Qt::AA_UseHighDpiPixmaps
X-Git-Tag: travis-deploy-test~369
X-Git-Url: https://git.quassel-irc.org/?p=quassel.git;a=commitdiff_plain;h=d29a6e9521e27e5d4d86fec82b5daa71085f87a5

Use Qt::AA_UseHighDpiPixmaps

This will fix some issues... and introduce new ones:

* Some pixmaps are now cut
* Old banner pixmap still pixelated
* Overall looks much less pixelated

Resolves GH-248.
