OLED care - move windows periodically in diagonal directions

[j4r3kb]

Since OLED monitors are becoming more popular, it could be a useful option. I use rectangle on an OLED monitor for a few months. Most often, I have two apps displayed that are 50/50 split vertically, and I can already see the line in the centre of the display in dark conditions.
I would quit splitting them evenly and just use "medium" sized windows if they would move on their own from time to time.

I don't have plans to add this in myself, but see no reason to turn down a good pull request for something like this.
