-------------------------+-------------------------
 I am not that familiar with the codebase and I couldn't find the exact
 point where this happens, but it seems that when you try to add multiple
 raster/vector maps in the GUI the maps get added one by one.

 From a usability point of view, this can get quite slow when you try to
 add many maps (e.g. 100+) and it can get excruciatingly slow when you have
 an already rendered map because the map gets re-rendered for each and
 every one map that we add.

 At the very least, the re-rendering of the existing map should only be
 done once; after all the maps have been added.
