    43  *	The app icon is a strange beast since it is specified only by file,

    45  *	When MBM files are used, the app/grid icon is a different size than the

    46  *	context icon, so two images are candidates, and the second one (if existing)

    47  *	is seen in the context icon.  When MIF files are used, the icon can be

    48  *	scaled for either position, so only the first image is used.

    49  *

    50  *	Note: this validation and this component do not get across the point

    51  *	that the app/grid icon may be different, so the user needs to find this

    52  *	out from experience.
