How to increase tooltip size for content in Eclipse / PDT

Question

I use PDT with Eclipse, and Content Assist tooltips (for example, to describe class methods) are too small to be useful. Usually only the first few words are visible. Is there any preference to increase their size? I have a lot of screen real estate, so I want to make them a lot bigger.

thanks

Edit: Maybe I'm using the wrong terminology - I'm talking about hints like PHPDoc. Here is a screenshot:
