Comment # 14 on bug 1022830 from Fabian Vogt

I packaged a test package with the partial revert and it seems to work for me.
The DPI settings are now respected by GTK3 applications, while they're not with
libgtk-3-0 from 42.3.

Note that firefox in 42.3 is still using GTK 2, so not affected.
I used nemo instead for testing.

Please confirm that it fixes the issue.
