Git commit 45a68ef44acad7ef0988fc0b040e5cf693b5ba53 by Harald Sitter.
Committed on 02/05/2019 at 12:05.
Pushed by sitter into branch 'Applications/19.04'.

Enable high-dpi pixmaps to ensure icons look correct with high-dpi scaling

This should work properly as-is, the only custom pixmap logic we seem to
have is in the block analyzer and that all runs through qpainter and is
correctly adjusted for devicepixelratio.
FIXED-IN: 19.04.1
