As a work-around, use TGA as your output format instead of PNG.  That TPN
file should not be there (should never have been created).  I'll have to
take a closer look at the PNG code to figure out what is going on.

You're mistaken.  :-)

However, everything within the range (start through start+depth) will be
totally in focus.  Sometimes you have to make the range significantly
shorter in order to get good blurring.  I want to add a fourth parameter,
which is the effect strength (a value of 2.0 would double the blurring).

That tpn file shouldn't exist.  Maybe it's a temporary file created by the
PNG code, but none of my code creates it directly.
