wake from sleep

[Andre Garzia]

Thomas,

I had to much coffee so the solution I thought is the most weird one you'll
ever see.

Create a simple image on your stack, then do something like:

   export snapshot from rect (the rect of img 1) to file
"~/Desktop/teste.jpg" as JPEG

wherever you want to check if the screensaver is running. You can also use
import snapshot which is better, or put the file in a better place. The
thing is, if you check the pixels in the imported image, they won't match if
the screensaver is running (or if another window is on top).

So, you can create this image on a offscreen coordinate in a temporary stack
that floats on top of everything, this way it will never ovelap. Then you
import and check the pixels. If they don't match something like a
screensaver is running filling all screen. If they do match then you're on
"interaction" mode....

should not drink much coffee.
