"tmpfile()" implementation in contrib/libtests/pngstest.c "tmpfile()" implementation in contrib/libtests/pngstest.c
Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io() Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io()
if there is no stdio.h support. if there is no stdio.h support.
Added an API and a number of assist macros to allow an application
that uses the simplified API write to bypass stdio and write
directly to memory.
Added some warnings (png.h) and some check code to detect *possible*
overflow in the ROW_STRIDE and simplified image SIZE macros. This
disallows image width/height/format that *might* overflow. This is
a quiet API change that limits in-memory image size (uncompressed) to
less than 4GByte and image row size (stride) to less than 2GByte.
