Changes

Min. Graph Parameter type change: texSize/width/.. for multipass-renderer: int -> int[]

"texWidth desired texture width for multipass-rendering.
 The actual used texture-width is written back when mp rendering is enabled, otherwise the store is untouched."

This allows the 'backend' to correct the texSize, ie in regards to GL_MAX_TEXTURE_SIZE .. etc.
Without this write-back, it would re-create the FBO for every frame.

JoglVersion: Avoid NPE if no caps are available.

Fix GLProfile/GLDrawableFactory bug: Recursion on default desktop device, since no profile was mapped.

GLDrawableFactory*:
  - Initialize defaultDevice, even if impl. is not available (no GL libraries for impl.), hence
  - getDefaultDevice() always returns a valid device
  - getIsDeviceCompatible() only returns 'true' if device is supported _and_ drawable factory is functional

GLProfile:
  - default-desktop-device becomes default-device even if the desktop-factory itself
    is not functional. This is due to the fact that the subsequent EGL-factory
    always handles desktop-devices (X11->EGL, GDI->EGL, etc).

enhancement: NWJNILibLoader.loadNativeWindow(..) returns true/false if loading was successful. Negative result causes proper exception in caller.

X11/GLX: Query X Server whether GLX is available (X11/SharedResourceRunner) ; Minor cleanups.

Before gathering GLX details and actually instantiate a X11/GLX shared resource,
we shall query whether GLX is actually available.

Since GLX availability is being queried on the server side,
more changes are required for the X11GLX* impl,
eg. not using X11GLXGraphicsConfigurationFactory and fall back to
X11GraphicsConfigurationFactory.

Cleanup DEBUG flags of *GraphicsConfigurationFactory (Use the common 'nativewindow.debug.GraphicsConfiguration')

X11: Fix unavailable GLX (Server): Use fallback GraphicsConfigurationFactory (X11GLX -> X11)

- GraphicsConfigurationFactory.registerFactory(..) returns previous mapped GraphicsConfigurationFactory.
  This allows daisy chaining of GraphicsConfigurationFactory, in case one is not suitable.

- X11GLXGraphicsConfigurationFactory:
  - Store the previously mapped factory as fallback
  - choose*Impl(): If GLX is not available, use fallback

Include GraphicsConfigurationFactory in lifecycle (initSingleton/shutdown) - fixes recursion on fallback GraphicsConfigurationFactory

.. also validate the X11 GraphicsConfigurationFactory in X11GLXGraphicsConfigurationFactory and fail fast
