to make it easier to remove unwanted capabilities via the compile line
Made some corrections to grammar (which, it's) in documentation (Greg).
Corrected example.c, use of row_pointers in png_write_image().

Corrected several statements that some compilers interpret as illegal use
of side effects in pngrutil.c and pngtrans.c, that were introduced in
version 1.0.1b
version 1.0.1d [May 24, 1998]
Corrected several statements that used side effects illegally in pngrutil.c
and pngtrans.c, that were introduced in version 1.0.1b

Fixed error in example.c with png_set_text: num_text is 3, not 2 (Guido V.)
Changed several loops from count-down to count-up, for consistency.
version 1.0.1e [June 5, 1998]
Revised libpng.txt and libpng.3 description of png_set_read|write_fn(), and
added warnings when people try to set png_read_fn and png_write_fn in
the same structure.
Added a test such that png_do_gamma will be done when num_trans==0
for truecolor images that have defined a background. This corrects an
error that was introduced in libpng-0.90 that can cause gamma processing
to be skipped.
Added tests in png.h to include "trans" and "trans_values" in structures
when PNG_READ_BACKGROUND_SUPPORTED or PNG_READ_EXPAND_SUPPORTED is defined.
Add png_free(png_ptr->time_buffer) in png_destroy_read_struct()
Moved png_convert_to_rfc_1123() from pngwrite.c to png.c
Added capability for user-provided malloc_fn() and free_fn() functions,
and revised pngtest.c to demonstrate their use, replacing the
PNGTEST_DEBUG_MEM feature.
