are you talking about approximated stats, isn't it? Because in this moment
the QgsRasterProvider compute full stats only, so the process can require
a lot of time.
In addition, I think we should re-style the piece of the raster Layer Property
dialog to set min/max (I know there's a ticket yet):
- the checkboxs are not checked whenever at least one should be,
- "Estimated (faster)" compute only approximated max/min, instead "Actual
(slower)" compute full stats (why? shouldn't compute min/max either)?
- the "Load" button is far away from the checkboxes (I thought them was
unrelated).
