Hi hooovahh,
My controls are already vector based, I've imported the decals from an EMF file and they do scale really well as you can see here:
But you can also see they look bad without anti-aliasing. I already had the EnableSecretPopups=True set for getting the scaling behaviour of these controls to be correct, it's a shame it doesn't expose more functionality!
Nice tip on looking at the DSC toolkit controls, I'll take a look at this to see if I can misuse any of the controls.
