another customizing request concerning the use of mdi:icons and their appearance.
please see https://github.com/Templarian/MaterialDesign/issues/3057#issuecomment-397065190 for their advice how to proceed and see if custom-ui or hassio can be adapted to allow for positioning the icons like:
mdi:lightbulb:flip-h
mdi:lightbulb:rotate-45
it all started with my request, which was met recently, for a dedicated mdi:desk-lamp 
which id love to be able to flip horizontally for obvious reasons, having a right and a left desk-lamp…
could this be realized, and what would be the best way to proceed?
thanks,
Marius
