// The Mac NGLayout is not based on shared libraries yet.
// All the DLLs are built as static libraries and we present them as
// shared libraries by redefining PR_LoadLibrary(), PR_UnloadLibrary()
// and PR_FindSymbol() below.
//
// If you add or remove shared libraries on other platforms, you must
//	- Add the library name to the defines below.
//	- Rename the "NSGetFactory" and "NSCanUnload" procs for the Mac:
//    just append the library name to the function name.
//	- Add the library and its procs to the static list below.
