MessageClip (string message, int "width", int "height", bool "shrink", int "text_color", int "halo_color", int "bg_color")
MessageClip produces a clip containing a text message; used internally for error reporting.
Arial font is used, size between 24 points and 9 points chosen to fit, if possible, in the width by height clip.
If shrink is true, the clip resolution is then reduced, if necessary, to fit the text.
