taskbar icons corrupted

[GoogleCodeExporter]

Taskbar widgets are shown corrupted when a window is focused, moved or closed. 
I've seen at most one widget corrupted at a time which then recovers after some 
window events.

On a related subject, task widgets get redrawn on every window event, like if 
they springed.

Corruption only comes in when GTK apps come in the way, not only reporting bad 
offsets in their icon data but obviously corruptin the whole NETWM-compliant 
algorythm of reading the icons (btw, this is confirmed in the bug-tracking 
systems of several WMs)

As of now, I have no idea on how and why this happens. I'll keep researching on 
that topic, but I'd really appreciate any user input.
Thus, the ticket is set back to 'New' again

It appears that GTK apps tend to misreport their dimensions to 
XGetWindowProperty (they can actually provide a smaller icon from time to time, 
resulting in memmove/memcpy carrying garbage. The fix is not ready yet but I 
hope this early report helps someone googling for a solution for a simiral 
problem)

Implementing the request standing in issue #47 made the problem obvious, plus 
it gave a chance to debug the current issue further. Will proceed on the 
current issue once any significant progress is made with issue #47
