Unsolved Qt Labs Controls & icon resources

[morte]

I trying to place an familiar ToolButton with icon. ToolButton have no property like iconSource so i set Image to background:

ToolButton {
	background: Image {
		source: icon("ic_chevron_left_white_24dp.png");
	}
}

From here i meet issues with bad image appearance (size/stretching/etc. )

In Qt Quick Controls 1 i can set an ldpi/mdpi/hdpi/etc. icon image depending on screen DPI and ToolButton icon looks as it should.
Qt Labs Controls designed to be used with new Qt 5.6 scaling feature (Qt::AA_EnableHighDpiScaling), what is proper way to deal with icon resources in Qt Quick Controls 2 application?

icons depend on DevicePixelRatio and are named this way:

myIcon.png - corresponds to 1.0 and mdpi - use this name in qml
myIcon@2x.png - 2.0 and xhdpi
myIcon@3x.png - 3.0 and xxhdpi
myIcon@4x.png - 4.0 and xxxhdpi

if you want to know the DevicePixelRatio:

C++
qApp->primaryScreen()......
