Of course not. But what about a configuration option that allows you to 
choose sw rendering?
Maybe a message to [gemwin], or some options you could set somewhere at

That's bad indeed. Sometimes it happened to me that on some machine the 
rendering was slow like hell, so most likely for some reason the 
hardware was not detected correctly and software rendering was being 
used, but I had no way to be sure of that.

Couldn't GEM simply print out a message telling whether hardware 
acceleration is available or not??
