JOGL (Windows):

    - WindowsWGLDrawableFactory is using [singleton] shared dummy resources for
        - Drawable and Context
      which are utilized in case they are needed ..
      They are removed at shutdown call

    - GLCapabilities
        - Set pbuffer as the HW capabilities show,
          hence onscreen && pbuffer is valid

        - DefaultGLCapabilitiesChooser: Respect PBuffer selection (fixed)
          Only skip a config, if request is !onscreen && pbuffer, but pbuffer n/a

Tests:
    - JUnit Passed (Windows32: Chromium - Except PBuffer (n/a)
