Under some conditions, 16-bit grayscale images aren't properly
expanded to rgb, because png_read_start_row() returns too small a
value of max_pixel_depth when png_set_filler() has also been called.
STATUS: Fixed in libpng-1.0.2a

When reading interlaced images with a progressive reader, in some

When using the filler transformation, the filler isn't written
into the leftmost pixel of each row.
Also, the filler operation isn't being done right when writing
files. Some code that was removed from png_set_filler() in
libpng 1.0.1a shouldn't have been removed.

"static pngcharp tIME_string" should be changed to
"static char tIME_string[30]" in pngtest.c
Also -- December 30, 1998 -- there are some misplaced brackets in
pngtest.c that cause pngtest to try to write a tIME chunk
even when no tIME chunk was present in the source file.

Order of byte-swap and shift operations seems to be incorrect in
png_do_write_transformations()
