This btw points out another circular dependancy between the texture and the JQuad - a texture owns a bunch of JQuads, yet the renderer uses JQuads and always assumes that the texture is valid. We're going to need to add more defensiveness to JGE to protect against this. Other changes in this check-in: WResourceManager doesn't derive from JResourceManager anymore. It actually didn't require anything from the base, so I killed the dependency. Also cleaned up the notion of a WTrackedQuad in the WCachedResource - it didn't need a separate class, just a better container. I've build this & tested against PSP, win, linux, QT (linux). I haven't tried against iOS and QT Win, or Maemo. If these other platforms are broken, I apologize in advance! - I'm hoping it should be fairly simple to put them back into play.
