This implements an API and provides a number of assist macros to allow an application which uses the simplified API write to bypass stdio and write directly to memory. It also includes 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. A quiet API change that limits in-memory image size (uncompressed) to less that 4GByte and image row size (stride) to less than 2GByte.

This "contrib" directory contains contributions which are not necessarily under the libpng license, although all are open source. They are not part of libpng proper and are not used for building the library, although some are used for testing the library via "make check".
