Subject: GLJPanel: Impl. is GLProfile agnostic; Use
GLDrawableFactory.createOffscreenDrawable(..) for common OffscreenBackend
(dropping pbuffer/software); Flip FBO w/ GLSL texture renderer.
- Implementation is GLProfile agnostic
- Shall work on ES2, GL2, .. etc
- Use GLDrawableFactory.createOffscreenDrawable(..) for common OffscreenBackend (dropping pbuffer/software)
- Leave offscreen selection to common factory code, favoring FBO
- Flip FBO w/ GLSL texture renderer
- Faster on low CPU machines
- Enabled if GL2ES2 and FBO offscreen
