I'm working on rolling out SW2016. With the interface change, all of my custom macro icons look like crap. They are 16x16 bitmaps and don't scale well in the new UI. I have dozens of them, and I hate to have to redo them, but I'm embarrassed to roll it out like it is. What is the best way to design them so they look good in all of the various scaling options?

Also, I was amazed to see that there is no option for using vector images on the macro buttons. The rest of the interface scales so nicely, why not my macro icons?

Btw, I'm on SW2016 sp 3.
