Changes since the last public release (1.2.18):
version 1.2.19beta1 [May 18, 2007]
Changed "const static" to "static PNG_CONST" everywhere, mostly undoing
change of libpng-1.2.17beta2. Changed other "const" to "PNG_CONST"
version 1.2.19beta2 [May 18, 2007]
Fixed png_do_expand() to only use the appropriate bits of tRNS value.
version 1.2.19beta3 [May 20, 2007]
Add some "png_byte" typecasts in png_check_keyword().
Write new_key instead of key in zTXt chunk.
version 1.2.19beta4 [May 21, 2007]
Add png_snprintf() function and use it in place of sprint() for improved
defense against buffer overflows.
version 1.2.19beta5 [May 21, 2007]
Fixed png_handle_tRNS() to only use the appropriate bits of tRNS value.
Changed handling of more unused parameters, to avoid compiler warnings.
Removed some PNG_CONST in pngwutil.c to avoid compiler warnings.
version 1.2.19beta6 [May 22, 2007]
Added some #ifdef PNG_MMX_CODE_SUPPORTED where needed in pngvcrd.c
Added a special "_MSC_VER" case that defines png_snprintf to _snprintf
version 1.2.19beta7 [May 22, 2007]
Squelched png_squelch_warnings() in pnggccrd.c and added an
#ifdef PNG_MMX_CODE_SUPPORTED block around the declarations that caused
the warnings that png_squelch_warnings was squelching.
version 1.2.19beta8 [May 22, 2007]
Removed __MMX__ from test in pngconf.h.
version 1.2.19beta9 [May 23, 2007]
Made png_squelch_warnings() available via PNG_SQUELCH_WARNINGS macro.
Revised png_squelch_warnings() so it might work.
Updated makefile.sgcc and makefile.solaris; added makefile.solaris-x86.
version 1.2.19beta10 [May 24, 2007]
Resquelched png_squelch_warnings(), use "__attribute__((used))" instead.
version 1.2.19beta11 [May 28, 2007]
Return 0 from png_get_sPLT() and png_get_unknown_chunks() if png_ptr is NULL;
changed three remaining instances of png_strcpy() to png_strncpy() (David
Hill).
Make test for NULL row_buf at the beginning of png_do_read_transformations
unconditional.
version 1.2.19beta12 [May 28, 2007]
Revised pnggccrd.c.
version 1.2.19beta13 [June 14, 2007]
