position_window_absolute might not work in all window managment schemes

[i509VCB]

WLCS at the moment uses position_window_absolute to place a window somewhere in the compositor coordinate space. However this type of behavior isn't going to be supported by every type of window management solution inside the compositor.

Tilers come to mind for an example of where placing a window at an absolute position in wlcs would conflict with how window management is done.

I guess the question then is how would position_window_absolute be adjusted to handle both types of window management concepts (tiling and floating) or would some tests like pointer_movement need a tiling mode?
