Description

When importing and adding a raster into a GRASS mapset, the layer is renderer with the wrong stretching and it is necessary to hit "local histogram stretch" to have the color map looks the same as the original raster. More in general when handling a GRASS raster, there is a difference in the colormap when hitting "local histogram stretch" or "stretch histogram to full dataset" even if the raster is being rendered at full extent -> in this case the two color maps should look the same.

Tested on master.
