I didn't (mean to) say that the dimensions were negative. The result
of the multipliction is. Coord (imageWidth and imagHeight) is really an
Int16 (signed). Gcc promotes all members to the largest (Int16), so
320x300x4 = 384000 ($5dc00) as a (signed) Int16 $dc00 = -9216. And as a
UInt32 $ffffdc00 = 429498080, easily bigger than 480000.
