Hi,

I have a wish about display, but maybe it's not concerning the "generic 
GUI".
It will be cool if the display resolution where "defaulted" to screen 
resolution when the "region resolution" is to big. Currently grass 
display all the cells, even if they aren't visible. With high 
resolution, display is very slow.
Sometimes it could be fine to have a high resolution for calculation and 
be able to pan without waiting.
I don't know how difficult it is, though.
