I'm having trouble with the WebApps icon being returned from the `/sites` method.

Namely, the image is composed of a larg white rectangle with a very small guy in the middle.

 - Why can't the guy take up the whole image?
 - Why is the background not transparent?

These issues lead to the following problem on my mobile site: *(look in the upper right corner)*

Compare that with one of the other sites:  
http://stackmobile.com/site.php?site=stackoverflow

 Is there nothing that can be done about this?
