Added png_access_version_number() function.
Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().

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).
