png.alib (from ambient) is required.

I'm not sure if depending on this private Ambient library is a good thing for various reasons:

- as its private we (as the Ambient developers) reserve us the right to change the API anytime (not very likely, but thats what private means).

- your class breaks with the upcoming release of MorphOS 2.0, because Ambient coming with MorphOS 2.0 does not have png.alib (or z.alib too) anymore.


I suggest you link libpng.a statically for now and as soon MorphOS 2.0 & SDK are released you simply recompile it with support for shared png.library (thats very easy and probably not even require change of source unless u really want to).

What is the difference between png.alib and png.library ?

In ambient sources there is a code:

#if USE_SHARED_LIBPNG
if ((PNGBase = OpenLibrary("png.library", 50)))
#else
if ((PNGLibBase = OpenLibrary("MOSSYS:Ambient/libs/png.alib", 1)))
#endif

so I have the similar code in my class waiting for Mos2.0 release.
