allow to specify the screen for images to open on the command-line
Submitted by houghi
Currently it is not possible to open images on different screens.
gimp --display :0.0 image1 will open the image on screen 0 en when you close it and then do
gimp --display :0.1 image2 it will open on screen 1.
When you do it without closing the first instance, the second will open it on display :0.0, screen 0, instead of the other screen.
I can then use
->View -> Move to screen to move the image, but it would be better if this can be done from the prompt and that --display acts as expected.
Also it would be good if you can decide to open the toolbox in one screen and the image on another screen (and even a second image on a third screen)
