Sprite edge glow?

[Majicpanda]

Is there any OnMouseEnter and exit type implementation I could do to make a sprite have a glow around it without having to make exact size glow for each sprite?

No there isn't, its not trivial to make a glow effect like this unless you use post processing, and that costs a lot of gpu

Maybe you can create a generic glow and just scale it depending on the sprite size?
It surely depends on the situation, but this generally works for most cases.
