[ gpsdrive ] How can I resize gpsdrive?

[Xamindar]

I am very new to gpsdrive and just got it installed on my carpc project. 
  One thing is driving me nuts about it though.  Unlike any other 
program I can't seem to be able to resize it.  Is there maybe some kind 
of config where I can tell it what resolution to use?  But that seems 
kinda difficult.  It seems to be cut off vertically and horizontally 
about a centimeter.  And of course it also goes down under my menubar. 
Is there any way to specify the resolution?  Or is this program hard 
coded to a specific resolution for some crazy reason?
