To be fair it should be noted that POV-Ray cannot read png files from a
partial/interrupted render as image maps/heightfields/... either. The
libpng function to load whole images ('png_read_image()') has problems
with them. Reading the image line by line ('png_read_row()') helps (this
is what i did for HCR-Edit and what POV does in 'Read_Rendered_Part()' for
continuing interrupted renders).
Maybe i should post a bug report concerning this? ;-)
