Description
ScummVM sometimes crashes if you change scaler during the CD intro. I think that is because update_screen() is being called from two different threads, without any safety net against races. This patch attempts to fix that, but I'm a bit uncertain about exactly which functions need to be guarded so it may be slightly wrong and/or incomplete.

Hm, I'll have a look at it later today. But it might be a better appproach to put the locking code into the SDL backend itself. Or not. Really need to try.

I put mutex code into the SDL backend, which should make this patch obsolete. Note that other backends (morphos, palmos, wince,...) may have to be enhanced to support multiple threads properly, too.

scaler changing works fine here with cvs now, closing as I don't see a reason for this to stay open
