Subject: Tested: - Linux / X11 / GL3 / GL2 / ES1 / ES2 - Using
 etc/profile.jogl JOGL_ALL . ./setenv-jogl.x86.sh JOGL_ALL - Java2D/GLJPanel:
 demos.jrefract.JRefract - GLCanvas: demos.gears.Gears - Newt/Nativewindow
 (demos.GLInfo, demos.es2.RedSquare, demos.es2.RedSquare) - with multiple
 instances of different GL profiles, ie java demos.es1.RedSquare -GLES2 -GLES1
 java demos.GLInfo -GLES2 -GL2 - GL 3.1 test with demos.GLInfo java
 demos.GLInfo -GL3 java demos.GLInfo -GL3 -GL2 with NVIDIA 180.37.05

JOGL
    Enable parallel GLProfiles:
        - GL holds it's GLProfile

        - GL / GLBase added:
            hasGLSL()
            getGLProfile()

        - Removed all hardcoded GLProfile checks

        - Make GLProfile an instance of GLCapabilities

        - GLCapabilities needs GLProfile in constructor,
          or null for the default GLProfile

        - All GLProfiles are singelton mapped objects,
          setup and verified at static init.

        - All GLDrawableFactories in GLDrawableFactory are singelton objects,
          setup at static init.

        - GLDrawableFactories.getFactory() needs an argument,
          which leads to GLProfile, ie
          NativeWindow, AbstractGraphicsConfiguration, GLCapabilities or GLProfile.

        - EGLDrawableFactory takes GLProfile as an argument,
          being able to take the singleton role as ES1 or ES2

        - EGLDrawableFactory loads ES & EGL libraries _local_,
          otherwise the symbols produce a collision (Unix/PC-Emulation).
          TODO: Check on Windows/WinCE !

        - Fixing etc/profile.jogl JOGL_ALL

    EGLGraphicsConfigurationFactory
        - Added eglGetConfigs -> GLCapabilities -> eglChooseConfig,
          in case the simple eglChooseConfig fails.

        - Using given chooser, is null, use DefaultGLCapabilitiesChooser

    Moved FixedFuncUtil.class -> jogl.util.jar,
          otherwise the FixedFuncUtil pipeline cannot be used without emulation.

    GLDrawable
        Rename getChosenGLCapabilities() -> getGLCapabilities(),
               since all GLCapabilities access functions return the current state.
        Add getGLProfile()

    NativeLibLoader[Base]
        Added 'addLoaded' and 'isLoaded', so all LoadAction implementation
        can use it and circumvent double library loading.

    GlueGen
        Split openLibrary -> openLibraryLocal / Global,
              utilizing as an optional flag (global), which is true per default.
        TODO: How to do this on Windows ?

    TODO: Verify Windows and MacOSX !!
