Uriah is a desk accessory which displays the system or application heap.
If your application services desk accessories, you can watch the
heap change.  In any case, you can play with other desk accessories.
The heap appears as a rectangular block consisting of vertical bands
of patterns.  The bands representing low to high memory run from top
to bottom of the rectangle, then top to bottom of the next band to
the right.  The bands are 8 pixels wide.
The patterns are:
Black:		Free
Striped:*	Relocatable, Unlocked, and Purgeable
Dark Gray:	Relocatable, Unlocked, but not Purgeable
Light Gray:	Relocatable, but Locked
White:		Not Relocatable
----------------------------------------------------------------
* This means a vertical band of 3 black, 2 white, 3 black pixels.
If flanked by black (Free) bands, this just looks like a narrow
white band.
