[Qgis-developer] Deactivate raster icon generation by default

[Andreas Neumann]

 Hi,

 A discussion on the german fossgis-user group revealed that generating 
 raster previews slows down raster loading a lot. Esp. for VRT raster 
 catalogs.

 Can we set this setting (Settings -> Options -> Canvas and Legend -> 
 Create Raster Icons (may be slow)) to off by default for new users?

 I think performance is much more important than raster icons in the 
 legend. In >90% cases you cannot see a think in these small raster icons 
 anyway. Also, a new user would not have the idea to turn this particular 
 setting off to speed up raster loading. Even I was not aware of it.

 Thanks,
 Andreas
