[REQUEST] - Effect border modifier

[averrin]

Is your feature request related to a problem? Please describe.
I'm working on Effect Editor and I want to display distinction between different effects, e.g., local/visible for users.
This "highlight" or "mark" should be bound to effect and be move/rotation/scale proof.

Describe the solution you'd like
An effect section modifier like border(color, width, style)

Describe alternatives you've considered
Richer API for geometric figures with autosize option to match effect's boundingRect.

Additional context
I tried to use text modifier. But it's not rotation/scale proof.
