[GRASSLIST:2773] Raster overlaying

[SWlab]

Hello,
Would there be any way to display layers of rasters and/or vector areas on top 
of a given background, in a semi-transparent way ? The d.rast -o option works 
in an all/nothing transparency. Same thing with d.vect.xxx. Are there nay 
plan to implement such a feature ? Did anybody write a script that would 
automatize the creation of such a picture in GIMP, for example (like 
exporting each layer, with the same dimensions, as a series of pictures ?)
Thanks for any help/suggestion
P.
