[gcompris-devel] Small display bug

[pgeorges]

when entering and leaving many times the different board collections 
using the home icon (bottom right), this icon gets darker and darker.
I don't want to dig into code, but I suppose Bruno you've got the 
solution :-)

Note that I switched all wav files to ogg, making gcompris work better 
with my current configuration (otherwise I missed some short sounds) ...
