Seamless Integration of an FBObject based GLFBODrawable as GLOffscreenAutoDrawable.FBO and as an OffscreenLayerSurface's drawable (OSX) - Fix Bugs 569 and 599

Summary:
=========
The new FBObject based GLFBODrawable implementation allows the seamless utilization of
FBO offscreen rendering in single buffer, double buffer and MSAA mode.

The GLFBODrawable uses a parent drawable based on a
dummy surface to allow a GLOffscreenAutoDrawable.FBO creation
or a mutable surface supporting an existing offscreen layer surface (OSX CALayer).

Offscreen GLDrawable's and GLOffscreenAutoDrawable's can be selected via the
GLCapabilities. If simply !onscreen is selected in the caps instance w/o enabling FBO, PBuffer or Bitmap,
the factory will automatically choose regarding availability:
   FBO > PBuffer > Bitmap

Double buffering is supported in MSAA more (intrinsic) and explicit in non MSAA.
It is preferred when delivering resources (texture id's or framebuffer names)
to a shared GLContext.
This is demonstrated in (emulates our OSX CALayer implementation):
  TestFBOOffThreadSharedContextMix2DemosES2NEWT,
  TestFBOOnThreadSharedContext1DemoES2NEWT
and with the OSX JAWT OffscreenLayerSurface itself. FBO is the preferred choice.

+++

Offscreen drawables can be resized while maintaining a bound GLContext (e.g. w/ GLAutoDrawable).
Previously both, drawable and context, needed to be destroyed and recreated at offscreen resize.
Common implementation in GLDrawableHelper is used in the implementations
(NEWT's GLWindow, AWT GLCanvas, SWT GLCanvas).

Tested:
=======

Manually run all unit tests on:
  - Linux x86_64 NVidia/AMD/Mesa3d(ES)
  - OSX x86_64 NVidia
  - Windows x86_64 NVidia
  - Android arm Mali-400/Tegra-2

No regressions.

Disclaimer:
===========
This feature is committed almost in one patch.

Both previous commits were introducing / fixing the capabilities behavior:
 90d45928186f2be99999461cfe45f76a783cc961
 9036376b7806a5fc61590bf49404eb71830de92f

I have to appologize for the huge size and impact (files and platforms) of this commit
however, I could not find a better way to inject this feature in one sane piece.

NativeWindow Details:
=====================

Complete decoupling of platform impl. detail of surfaces
implementing ProxySurface. Used to generalize dummy surfaces and EGL surfaces
on top of a native platform surface.
  - ProxySurface.UpstreamSurfaceHook -> UpstreamSurfaceHook
  - abstract class ProxySurface -> interface ProxySurface + ProxySurfaceImpl
  - Misc. implementations

JOGL Details:
=====================

FBOObject: API Change / Simplification & Usability
  - Removed reference counter to remove complexity, allow user to choose.
  - Add 'dispose' flag for detachColorbuffer(..), allowing to keep attachment alive
  - Fix equals operation of Attachment
  - Check pre-exising GL errors
  - Interface Colobuffer gets lifecycle methods
  - Add static factory methods to create Attachments w/o FBObject instance
  - Reset:
    - Clip min size to 1
    - Keep alive samplingSink, i.e. don't issue resetMSAATexture2DSink(..).
      It gets called at syncFramebuffer()/use(..) later on before actual usage.
      This allows the consumer to utilize the GL_FRONT buffer until (e.g.) swap.
  - misc bugfixes

GLOffscreenAutoDrawable: API Change
  - Reloc and interfacing
  - class com.jogamp.opengl.OffscreenAutoDrawable -> javax.media.opengl.*
    interfaces GLOffscreenAutoDrawable extends GLAutoDrawable
               GLOffscreenAutoDrawable.FBO extends GLOffscreenAutoDrawable, GLFBODrawable
  - Added general implementation and FBO specialization
  - Replacing GLPBuffer (deprecated) .. usable for any offscreen GLDrawable via factory

GLAutoDrawable:
  - Add 'GLDrawable getDelegatedDrawable()'
  - Refine documentation of setContext(..), remove disclaimer and fixme tags

GLDrawableFactory:
  - Refine API doc and it's selection mechanism for offscreen.
  - Add createOffscreenDrawable(..)
  - Add createOffscreenAutoDrawable(..)
  - Add canCreateFBO(..)
  - Mark createGLPbuffer(..) deprectated

Mark GLPBuffer deprecated

New: GLFBODrawable extends GLDrawable

GLCanvas (AWT and SWT): Add offscreen resize support w/o GLContext recreation

GLAutoDrawableBase .. GLWindow:
  - Add offscreen resize support w/o GLContext recreation
  - Remove double swapBuffer call
  -

GLBase/GLContext:
  - Add:
    - boolean hasBasicFBOSupport()
    - boolean hasFullFBOSupport()
    - int getMaxRenderbufferSamples()
    - boolean isTextureFormatBGRA8888Available()

GLContext: Fix version detection and hasGLSL()
  - Version detection in setGLFunctionAvailability(..)
    - Query GL_VERSION ASAP and parse it and compare w/ given major/minor
    - Use parsed version if valid and lower than given _or_ given is invalid.
    - Use validated version for caching (procaddr, ..), version number, etc.

  - Fix hasGLSL()
    Since 'isGL2ES2()' is true if 'isGL2()'
    and the latter simply alows GL 1.*, we confine the result to a GL >= 2.0
    on desktops. FIXME: May consider GL 1.5 w/ extensions.
    -  return isGL2ES2();
    +      return isGLES2() ||
    +             isGL3() ||
    +             isGL2() && ctxMajorVersion>1 ;

GLDrawableImpl:
  - Add 'associateContext(GLContext, boolean)' allowing impl.
    to have a (weak) reference list of bound context.
    This is was pulled up from the OSX specific drawable impl.
  - swapBuffersImpl() -> swapBuffersImpl(boolean doubleBuffered)
    and call it regardless of single buffering.
    This is required to propagate this event to impl. properly,
    i.e. FBODrawable requires a swap notification.
  - Clarify 'contextMadeCurrent(..)' protocol

GLDrawableHelper:
  - Add resize and recreate offscreen drawable util method
  - Simplify required init/reshape calls for GLEventListener
  -

GLGraphicsConfigurationUtil:
  - fixWinAttribBitsAndHwAccel: Reflect sharede context hw-accel bits
  - OSX has no offscreen bitmap, use pbuffer
  - use proper offscreen auto selection if offscreen and no modes are set

EGL Context/Drawable/DrawableFactory: Abstract native platform code out of base classes
  - Use EGLWrappedSurface w/ UpstreamSurfaceHook to handle upstream (X11, WGL, ..)
    lifecycle - in case the EGL resource is hooked up on it.

Invisible dummy surfaces: All platforms
  - size is now reduced to 64x64 and decoupled of actual generic mutable size
  - fix device  lifecycle, no more leaks

+++

OSX
====

Enable support for GLFBODrawableImpl in offscreen CALayer mode
  - NSOpenGLImpl: hooks to calayer native code
  - calayer code:
    - allows pbuffer and texures (FBO)
    - decouple size and draw calls avoiding flickering
    - enable auto resize of calayer tree

MacOSXCGLContext:
  - NSOpenGLImpl:
  - Fix false pbuffer 'usage', validate the pointer
  - If !pbuffer, copy other window mode bits of caps
  -

MacOSXCGLGraphicsConfiguration:
  - Only assume pbuffer if !onscreen
  - Remove reference of native pixelformat pointer

Native code:
  - use 'respondsToSelector:' query before calling 'new' methods
    avoiding an error message where unsuported (prev. OSX versions)
  - if monitor refresh-rate is queried 0, set to default 60hz
  - add missing NSAutoreleasePool decoration

+++

Android / NEWT:
===============

Issue setVisible(..) w/o wait, i.e. queue on EDT,
@Android surfaceChanged() callback. Otherwise we could deadlock:
   setVisible(..) -> EDT -> setVisibleImpl(..) -> 'GL-display'.
the latter may may cause havoc while Android-EDT is blocked [until it's return].
