Revised comments in png_set_read_fn() and png_set_write_fn().
-version 1.4.0beta50 [March 9, 2009]
+version 1.4.0beta50 [March 21, 2009]
Use png_calloc() instead of png_malloc() to allocate big_row_buf when
reading an interlaced file, to avoid a possible UMR.
+ Undid revision of PNG_NO_STDIO version of png_write_flush(). Users
+ having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined
+ or supply their own flush_fn() replacement.
+ Revised libpng*.txt and png.h documentation about use of png_write_flush()
+ and png_set_write_fn().
+ Removed fflush() from pngtest.c.
+ Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h
+
+version 1.4.0beta51 [March 21, 2009]
+ Removed new png_fileno() macro from pngconf.h .
version 1.4.0betaN [future]
