Minor bugfix version. Plobary a good update.
Fixes:
Revised png_warning() to write its message on standard output by default
when warning_fn is NULL. This was the behavior prior to
libpng-1.2.9beta9.
Fixed string vs pointer-to-string error in png_check_keyword().
Added png_check_cHRM_fixed() in png.c and moved checking from pngget.c,
pngrutil.c, and pngwrite.c, and eliminated floating point cHRM
checking.
Added check for zero-area RGB cHRM triangle in png_check_cHRM_fixed().
In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant
check for all-zero coordinates that is detected by the triangle check.
Revised png_warning() to write its message on standard output by default
when warning_fn is NULL.
Corrected off-by-one error in bKGD validity check in png_write_bKGD()
and in png_handle_bKGD().
Revised bKGD validity check to use >= x instead of > x + 1
Merged with png_debug from libpng-1.4.0 to remove newlines.
Removed redundant check for key==NULL before calling png_check_keyword()
to ensure that new_key gets initialized and removed extra warning
(Arvan Pritchard).
Added PNG_TRANSFORM_STRIP_FILLER_BEFORE and
PNG_TRANSFORM_STRIP_FILLER_AFTER conditionals and deprecated
PNG_TRANSFORM_STRIP_FILLER (Jim Barry).
