[Qgis-developer] Raster providers

[Giovanni Manghi]

Hi Radim,

unfortunately the "temporary? ugly fix for not georeferenced images", as
you call in the commit, does not seem to work fine with the
georeferencer.

If you open a non-georeferenced image in the georeferencer it will not
show in the tool window.

Cheers
