Changes

Bug 577: Disable debug message XInitThreads() called (only enabled in native debug mode).

WWW: Add GeoGebra; Prio JOGL2 usage

WWW: Cleanup some descriptions, text alignment

NEWT Input- Mouse-Event: Consitency of mouse button number; Add button -> button-mask func.

Fix Bug 571: X11 behavior, where the PRESSED button is not included in the native mask.

test scripts

TestGearsES2NEWT: fullscreen/above toggle print fullscreen/above state always

Bug 570: NEWT General/X11: Decouple setFullscreen() and setAlwaysOnTop(); Use window-static instances for runnable actions

NEWT General/X11: Decouple setFullscreen() and setAlwaysOnTop()
  - X11 fullscreen/above: Don't assume 'always-on-top' if switch to fullscreen.

  - WindowImpl: Remove relation between 'always-on-top' and fullscreen
    when quering and switching.

Use window-static instances for runnable actions
  - Removes temp objects for EDT runnables
  - Uses synchronization on action instance to avoid concurrency

Bug 556: Newt Mouse Synthetic Drag Event: Clear state if mouse enters/leaves window.

Since we cannot guarantee to have the pressed button information when receiving
the mouse move event, we synthesize the dragged event (move while mouse button pressed).

To simplify the situation and have a compromise,
we clear the mouse pressed states when mouse
enters or leaves the window to remove the dragged events at re-entering.

This seems more sensible, since dragging after re-entering the mouse shall not be expected.

EGLGraphicsConfigurationFactory: Add 'unregisterFactory()' static entry allowing to remove EGL/ES based factory

GLProfile/EGLDrawableFactory: Detect ANGLE (Windows D3D ES2 Emulation) and disable support per default.

We have to disable support for ANGLE, the D3D ES2 emulation on Windows provided w/ Firefox and Chrome.
When run in the mentioned browsers, the eglInitialize(..) implementation crashes.
This behavior can be overridden by explicitly enabling ANGLE on Windows by setting the property
'jogl.enable.ANGLE'.

EGLDrawableFactory:
  - destroy(): clear references and unregister factory, maybe triggered by GLProfile (ANGLE case)
  - getAvailableCapabilitiesImpl(): return empty list in case EGL/ES is n/a (ANGLE case)

NEWT/WindowImpl: Make all 'action' class instances final; Action's init() determines whether it shall be executed.

Fix Bug 560 and NEWT window closing behavior in general for all platforms.

- NEWT/WindowImpl:
  - 'void windowDestroyNotify()' -> 'boolean windowDestroyNotify(boolean force)', allowing to signal a forced close,
    as well as replying whether the window has been closed. (called by native code)

  - destroy(): set states before releasing the window lock

- NEWT/X11: Pass windowDeleteAtom for reconfigure window, in case of reparenting child to top-level

- NEWT/OSX:
  - Add 'BOOL windowShouldClose()' impl., ie. having a chance to reject the close attempt
  - Common impl. for 'windowShouldClose' and 'windowWillClose' -> 'windowClosingImpl'
    utilizing new 'windowDestroyNotify' code (see above).
    Fixes bug 560.

- NEWT/JOGLNewtApplet1Run: Refine out-of browser window behavior for window-close button
  - default: move NEWT window back to browser parent
  - closeable: close NEWT window

- jogl-test-applets: Add NApplet-Closeable test (Applet out-of browser window is closable)

JOGLNewtAppletBase: Minor cleanup

NEWT: Revert static/locked action instances due to possible deadlocks; class Window.ReparentAction -> enum Window.ReparentOperation

Revert static/locked action instances due to possible deadlocks
  - reverts commit: be59d561fd6ab8aa659e85cd962d38fffd1acb0a (partially)
  - reverts commit: 5742b1faa210401470032ef129e56a83c47fd046

  Even thought the idea of having no temp. objects is nice to have,
  using a static instance requires locking which introduces a deadlock
  in case the action is being issued from diff. threads.

class Window.ReparentAction -> enum Window.ReparentOperation (Minor API Change)
  Clarifies reparent operations using enums

Complete commit c9faebb8f8f6be4c0de4919a516b4692742bc13c: Use 'enum ReparentOperation' in test.

NEWT API Change 'WindowClosingProtocol': Use 'enum WindowClosingMode' instead of static final int values.

Test MovieCube: Allow recreation - Video is still not visible after recreation (detach window) on OSX (FF, Safari)
