title: Increase the height of the toolbar in an E4 application
body: <p>I've an E4 application where the toolbar needed a custom colored button. I'm using a ToolControl and creating a <a href="https://code.google.com/a/eclipselabs.org/p/opal/wiki/OButton" rel="nofollow noreferrer">OButton</a>. The problem is the button gets chopped off, Is there a way I can increase the height of the toolbar?</p>
