JNLP: Cache jogl-all-natives and jogl-cg-natives for linux-armv6 and linux-armv6hf.

Gluegen commit gluegen/commit/422d7a5eb53fca6642ebf4e8910d8b0311bb2597
Change/Lower ARM Requierements for GNU/Linux
changed the *native-linux-arm* jar names; update jnlp-files accordingly.

Due to the lack of OS Arch and ABI detection in JNLP launchers
force us download both armv6 armel and armv6hf armhf ABI jars on ARM.
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].
Windows scripts: bump to 1.6.0_35
Cleanup shutdown mechanism ; Fix X11/ATI SIGV at shutdown ; EGLDisplayUtil: Check for leaked display handles

GLProfile / all shutdown methods: Remove ShutdownType to remove complexity (not required)

Proper shutdown sequence:
  GLProfile - GLDrawableFactory+ - GLContext - NativeWindowFactory - [X11Util, OSXUtil, ..]

GLDrawableFactory: Always keep shutdown-hook alive, required for X11Util shutdown (@ JVMShutdown only)

X11Util: Shutdown
  - @ JVMShutdown only
  - If GL vendor ATI: close pending X11 display connections in proper order of creation.
    This finally removes the SIGV when shutting down the JVM on X11 w/ ATI driver.

EGLDisplayUtil: Add shutdown, allowing to validate whether leaked EGL display handles remain.
NEWT EDTUtil: Complete AWT and SWT impl. w/ Newt event dequeue thread (NEDT)

AWT and SWT impl. use the toolkit thread to deliver toolkit events and to
execute task. However, NEWT dispatches event using its own queue for NEWT events.
Adding a simple thread to dequeue those.

Remove 'EDTUtil.start()', since this is implicit @ invoke().
NEWT AWT Driver: Remove flashing (clear background @ update/paint method) ; Proper canvas size and direct events.
Fix window mode attribute bit FBO_BIT usage in platform dependent code (map it to native type) ; OSX Caps selection ; WGL/GDI BITMAP fix

Fix window mode attribute bit FBO_BIT usage in platform dependent code (map it to native type)
  All platform dependent winAttrBit mapping: 'nativeType -> winAttrBit' and 'GLCapabilities -> winAttrBits'
  shall replace FBO_BIT w/ the native type of the wrapper surface, i.e. WINDOW_BIT (X11, WGL, CGL) or PBUFFER_BIT (EGL).
  This condenses to changes in
    - EGLGraphicsConfiguration: EGLConfigDrawableTypeBits / GLCapabilities2AttribList

    - X11GLXGraphicsConfiguration: FBCfgDrawableTypeBits, XVisualInfo2GLCapabilities / GLCapabilities2AttribList

    - WindowsWGLGraphicsConfiguration: AttribList2DrawableTypeBits, PFD2DrawableTypeBits / GLCapabilities2AttribList

    - OSX CGL/NS requires changes in MacOSXCGLContext, i.e. fix the surface mode of
      NSPixelFormat2GLCapabilities, CGLPixelFormat2GLCapabilities results.
      This change is included in the upcoming commit (class is heavily edited).

OSX chooseGraphicsConfigurationStatic: Add missing 'GLGraphicsConfigurationUtil.fixGLCapabilities(..)' call
  - all platform impl. require to fix the given user caps due to the new offscreen auto selection mode

WindowsWGLGraphicsConfiguration*: ARB / GDI updateGraphicsConfiguration*()
  - ARB method detects early whether it's suitable for given HDC, i.e. in case of BITMAP (it's not here)
  - GDI methods detect failure while choosing PFD and doesn't care of DOUBLEBUFFER in case of bitmap (fixes BITMAP usage)

Capabilities/GLCapabilities:
  - Fix missing double-buffer check in GLCapabilities.equals()
  - add 'copyFrom(..)' method copy all data from give caps
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].
Merge remote-tracking branch 'xranby/jnlp-arch-armv6'
Disable double-buffer mode when offscreen-bitmap is chosen, remove dbl-buff bitmap test
