This should make it possible to build StepMania 5 on Mac OS X. The catch is that it will only work with Snow Leopard and up, but I think this is better than nothing. We can support PowerPC / 10.4-10.5 again when someone can make the old Xcode 3 project work.
This demonstrates the use of PNG_USER_CONFIG and pngusr.h
The makefile builds a minimal read-only progressive decoder with
embedded libpng, zlib and your system's X library.
Specify the location of the zlib source (1.2.1 or later) as ZLIBSRC
on the make command line.
Edit makefile if required, to find your X library and include files,
then
make ZLIBSRC=directory
If you prefer to use the shared libraries, go to contrib/gregbook
and build the rpng2-x application there.
