sourceSize documentation is not accurate for dpi-scaled screens

https://doc.qt.io/qt-5/qml-qtquick-image.html#sourceSize-prop says "[setting sourceSize to 1024x1024] ensures the image in memory is no larger than 1024x1024 pixels".

Looking at QQuickImageBase::load, it seems that sourceSize is scaled by devicePixelRatio. so for svgs and image urls (not entirely sure what that includes, see QQuickImageBasePrivate::updateDevicePixelRatio), this statement is not correct.

Generally, any hint in the docs how that property works together with dpi scaling would be appreciated.
