Still, I don't see a good reason to try to avoid making it available on the other platforms.  As I wrote elsewhere in the thread, maybe .icns can even turn out to be a good cross-platform icon solution.  And JPEG2000 might be useful in other contexts, too; however that comes at the cost of linking with yet another library.  As long as we ensure that when the library is missing, the ability to decode the larger versions of the icons is missing (or the ability to decode the icons at all is missing), and that doesn't cause any other problems at runtime, is there any other reason not to have it available?  It's not like we'd have to include the JPEG2000 decoder source with Qt, just have the ability to detect the library and compile the plugin only if it's there, right?
