/* In Cocoa-based xscreensaver, all hacks run in the same address space,
- so each one needs to get its own screen number. We just use a global
- counter for that, instead of actually trying to figure out which
- monitor each window is on. Also, the embedded "preview" view counts
- as a screen as well.
-
- Note that the screen number will increase each time the saver is
- restarted (e.g., each time preferences are changed!) So we just
- keep pushing the num_screens number up as needed, and assume that
- no more than 10 simultanious copies will be running at once...
+ so each one needs to get its own screen number. Believe what jwxyz
+ says about screen counts and numbers.
