Bug 1037 - FBObject: Add proper attachment size validation at init, reset and attachColorbuffer(..) / attachRenderbuffer(..)
GLJPanel: Enhance the class API-doc
GLJPanel: Only dump verbose debug on frameCount each frame if property 'jogl.debug.GLJPanel.Frames' is defined
GLJPanel: Enhance API doc on setSkipGLOrientationVerticalFlip(..)
Bug 1016 - GLJPanel Offscreen FBO size may exceed GL MAX TEXTURE SIZE, only use an FBO TextureAttachment if required

We only require an FBO TextureAttachment if using GLSL vertical flip,
otherwise we simply requires a color renderbuffer.

Further, the 'FBO fboFlipped' in GLSL vertical flip mode also simply requires a color renderbuffer.
