[pygtk] Removing "gaps" from ProgressBars

[Geoff Bache]

Hi,

I have got used to the look of my ProgressBar on Linux, PyGTK 2.4.13.
It is blue, solid and the text on it looks nice.

I recently tried to port it to Windows (using version 2.6.8) and find that 
it is now green with white "gaps" in it. Whatever colour I make the text,
it is nearly illegible because of these gaps.

I spent a while trying to figure out how to configure it but I failed to
alter either the colour or the gaps. There don't seem to be any relevant 
style properties, and changing "fg" changes the colour of the text, while
changing "bg" seems to have no effect.

Can anyone give a pointer on how to make the text more readable?

Thanks,
Geoff Bache
