padding around thumbnail items

Description
Currently, timeline video clips are tedious to look at, because each individual thumbnail item (ie: each "square" on a clip "filmstrip") is directly adjacent to another. There is no visual separation. For scenes where there is not much movement, it looks like a very long serie of the very same image, and is actually less useful than having no thumbnails at all.
I suggest adding a ~3px padding around thumbnail items to allow the eyes to discern them properly.
