New property: "Frame color" for Modern controls

[vix]

Using a modern control (see the attached slider, as an example) it's possible to change the frame color with "Customize control" window.

But during runtime execution this color can't be changed (see this discussion)

I suggest a new property "Frame color" that can be written during runtime.
