FUNCTION

Specify the left edge of a window. Usually, you shouldn't define a pixel value here but instead use one of the following macros:

MUIV_Window_LeftEdge_Centered:: window appears centered on the visible area of screen.
MUIV_Window_LeftEdge_Moused: window appears centered under the mouse pointer.

Default for this tag is MUIV_Window_LeftEdge_Centered.

As long as your window has a window id (MUIA_Window_ID), choosing a position is not that important. MUI will always remember a windows last position and size and these values will simply override your settings. Positioning and sizing should be completely under user control, a programmer doesn't need to worry about it.
