When - // the Java2D/JOGL bridge is active, this means that if we want to - // be able to share textures and display lists with the Java2D - // contexts, we need to use the CGL APIs rather than the NSOpenGL - // APIs on the JOGL side. For example, if we create a pbuffer using - // the NSOpenGL APIs and want to share textures and display lists - // between it and the Java2D back buffer, there is no way to do so, - // because the Java2D context is actually a CGLContextObj and the - // NSOpenGLContext's initWithFormat:shareContext: only accepts an - // NSOpenGLContext as its second argument. Of course there is no way - // to wrap an NSOpenGLContext around an arbitrary CGLContextObj. - // - // The situation we care most about is allowing a GLPbuffer to share - // textures, etc. with a GLJPanel when the Java2D/JOGL bridge is - // active; several of the demos rely on this functionality. We aim - // to get there by allowing a GLPBuffer to switch its implementation - // between using an NSOpenGLPixelBuffer and a CGLPBufferObj. In - // order to track whether this has been done we need to have the - // notion of a "mode" of both the MacOSXGLDrawable and the - // MacOSXGLContext. Initially the mode is "unspecified", meaning it - // leans toward the default (NSOpenGL). If sharing is requested - // between either a GLJPanel and a GLPbuffer or a GLCanvas and a - // GLPbuffer, the GLPbuffer will be switched into the appropriate - // mode: CGL mode for a GLJPanel and NSOpenGL mode for a GLCanvas. - // To avoid thrashing we support exactly one such switch during the - // lifetime of a given GLPbuffer.
