QString qt_findAtNxFile	(	const QString &	baseFileName,

Since

5.6 Attempts to find a suitable @Nx file for the given targetDevicePixelRatio Returns the baseFileName if no such file was found.

Given base foo.png and a target dpr of 2.5, this function will look for foo@3.nosp@m.x.pn.nosp@m.g, then foo@2x, then fall back to foo.png if not found.

sourceDevicePixelRatio will be set to the value of N if the argument is not \nullptr
