Added check for PNG_READ_INTERLACE_SUPPORTED in pngread.c; issue a warning
if an attempt is made to read an interlaced image when it's not supported.

+ Added check if png_ptr->trans is defined before freeing it in pngread.c
Modified the Y2K statement to include versions back to version 0.71
Fixed a bug in the check for valid IHDR bit_depth/color_types in pngrutil.c
Modified makefile.wat (added -zp8 flag, ".symbolic", changed some comments)

+ Added a check for info_ptr->free_me&PNG_FREE_TEXT when freeing text in png.c

Added png_access_version_number() function.
Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
Expanded libpng.3/libpng.txt information about png_data_freer().
-version 1.0.7beta13 [May 16, 2000]
+version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
warnings instead of errors, as pngrutil.c does.
Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
will actually write IDATs.
Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
- Make png_free_data() ignore its final parameter when freeing data that can
- have multiple instances (text, sPLT, unknowns).
-version 1.0.7beta14 [May 17, 2000]
+ Make png_free_data() ignore its final parameter except when freeing data
+ that can have multiple instances (text, sPLT, unknowns).
Fixed a new bug in png_set_rows().
Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
Added png_set_invalid() function.
Fixed incorrect illustrations of png_destroy_write_struct() in example.c.
+version 1.0.7beta15 [May 29, 2000]
+ Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
+ fewer error messages.
+ Rearranged checks for Z_OK to check the most likely path first in pngpread.c
+ and pngwutil.c.
+ Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
+ in libpng.txt/libpng.3 the need for applications to check this.
+ Changed names of png_default_*() functions in pngtest to pngtest_*().
+ Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
+ Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
+ Set each pointer to NULL after freeing it in png_free_data().
+ Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
+ macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos)
+ Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
