PixelOverlay-Clock.php works but I have questions...

[datajack]

I've been looking into overlays in general (display message via rest api) and PixelOverlay-Clock.php specifically. I can get writing to overlay to work just fine (on top of other content), and after a little bit of tinkering, I could get the script to display time in the correct time zone and HH format. A couple of questions:

1. Is there way to have a bit more control over the placement of text? The current options are center and scrolling in four directions. I'd like to place the clock in upper or lower right corner. Any way to set X/Y or some such?
Note: I've jsut created overlays with the same amount of pixels as the LED panel i'm using, so maybe the answer lies in the configuration of the overlay?

2. Once I start the clock script, how to I stop it again? The code comment says CTRL-C, but that doesn't seem very flexible 😉
