Warning before running analyses on too large rasters

If the user does not select an appropriate resolution for the resulting raster(s), it risks to get stuck with an excessive resolution, and too long processing time. I suggest to do a simple calculation of the resulting number of pixel before running analyses, and warn the user if this is too high.

I think this request could be satisfied by instead allowing cancellation of gdal algorithms. The native QGIS algorithms all have nice progress reports and support responsive cancellation already.

Agreed, thanks.

#27882 is implemented, so this could probably be closed.
