[Qgis-developer] Deactivate raster icon generation by default

[Andreas Neumann]

 Hi Matthias,

 Thank you - I don't think the threshold would be too useful. With the 
 VRT format the problem is probably that potentiall hundred/thousands of 
 files would have to be opened just to generate this small icon that is 
 of very limited use.

 Thank you for your fix!

 Andreas
