Comment 2 for bug 1534906

Okay, so from begin on. I was working on Mingw32 builds because I needed a good FOSS pdf viewer for Windows. Since this app doesn't use global icons on Windows I had to rely on the fallback icons. The svg icons worked fine on Windows 10 (but QtSvg lib needed to be in the directory) but weren't shown in Wine. So I replaced them with png versions and disabled the svg support (side effect: makes the whole bundle a bit smaller).
This is the shell script I use for building on Msys:

#!/bin/sh

# helper script for mingw32 builds on Msys

It works pretty well but I was wondering if it would make sense to add an option to use png fallback icons instead of svg ones.
