It's not quite true.
MacOSX choses a necessary image representation based on the current
transformations. Setting current transformation to scale 2x leads
that the high resolution image is drawn even on non HiDPI display.
There is a similar mechanism for the MultiResolution toolkit
images. The base image is drawn in case if the high-resolution image has
not been loaded yet.
It has an issue that if there is no one more repaint event the
image with high resolution is not shown.
I would suggest to move this topic to a separate issue.
