Summary: Virtual colour depth & full screen resolution?
           Product: Wine
           Version: 1.1.33
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2

Would it be technically possible to implement a virtual desktop that allows you
to set the colour depth and resolution, but then wine will stretch the virtual
desktop to full-screen or to a custom resolution?

What would happen if you fooled a game that needed 256 colour depth into
thinking that's what it is running in while it is actually running at 24bit?

I ask this as I am unable to change my colour depth and reduce my resolution
below 640x480. And even when I could change my colour depth it meant restarting
the X-server. I assume other people will also have this problem.
