Fix Capabilities ambiguity and explosion of queried available-list; Add FBO availability detection for EGL, WGL and OSX.

Introducing Capabilities 'bitmap' boolean, complementing the offscreen modes FBO and PBuffer.
This allows:
  1 - deterministic setting of the offscreen mode

  2 - utilizing auto configuration of offscreen mode, if !onscreen !FBO !PBuffer and !Bitmap

  3 - adding 'availability' semantic of 'onscreen' boolean,
      i.e. if onscree:=1 for a queried instance, the offscreen modes still indicate offscreen
      availability - see [4]

  4 - avoiding explosion of the availability list due to [3],
      one Capability entry reflect on- and offscreen settings.

Add FBO availability detection for EGL, WGL and OSX.

Tested manually w/ 'TestGLCapabilities01NEWT' on X11 [NV, ATI], WGL[NV], OSX[NV].
