Replaced and extended code that was removed from png_set_filler() in 1.0.1a.

Changed "static pngcharp tIME_string" to "static char tIME_string[30]"
|

Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk
|
||||
even when no tIME chunk was present in the source file.
|
||||
Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit.
|
||||
Fixed a problem in png_read_push_finish_row(), which would not skip some
|
||||
passes that it should skip, for images that are less than 3 pixels high.
