AlignRect

Psychtoolbox › PsychRects

rect=AlignRect(rect,fixedRect,side1,[side2])

Moves rect to align its center/top/bottom/left/right with the
corresponding edge(s)/point of fixedRect. Does "side1" and then "side2".
The legal values for side1 and side2 are 'center', 'left', 'right',
'top', and 'bottom'.
For backward compatibility, also accepts 1,2,3,4,5. You may use the
pre-defined constants RectLeft,RectRight,RectTop,RectBottom, but there is
no named constant for centering.
