Nope.


But you aren't restricted to using a single size of icons, or even tile coordinates on the screen.

You can use screen coordinates like this:

"WEST:256,SOUTH:128"

Which translates to 256 pixels from the left, 128 pixels from the bottom.

For the "x1,y1 to x2,y2" format, I'd say ditch it for most purposes. It's just easier to work in anchors and pixels and it's easier to build UI elements out of arbitrarily sized pieces. or just blast a whole menu background up on the screen at one time.
