Hi!

Sorry if this was reported/fixed before (it's not in Rune's list afaik).
Using a png in a height_field fails for me. Instead I get

Parse Error: Unknown image type in image_height_at.

The png renders fine as a height_field in Mega 0.6a and is loaded correct in
Micrografx Picture Publisher.
I post it to p.b-t.binaries if it's not a general png-problem.
