I created a Part with a toolbar that has two HandledToolItems. Those are of type Push and have an icon attached. I used the same icon as for HandledMenuItems (16x16).
While in Eclipse 3.x everything was rendered correctly, in Eclipse 4 the icons overlap the top border of the of the part and the border where the part header is rendered (don't know the correct name of it, but I attached a screenshot).
On comparing Eclipse 3.x with Eclipse 4, it seems the space for rendering the part header has shrunk.
Do I have to adjust something manually to make the icons fit again?
