GL2ES2 on Desktop
=================

GL2ES2 Profile with GL_ARB_ES2_compatibility:
    Extension is supported and recognized properly.
    It can be queried via GLContext.isGLES2Compatible()
    and impacts many ES2 related GL2ES2 wrapper functions
    like glShaderBinary(..).
    Having ES2 compatibility results in a full ES2 implementation
    even if using GL2ES2 via a desktop profile.
    Of course, ES2 extensions are not supported in this case.


Native GLES2 on Desktop
=======================

Ensure that the native ES2/EGL libraries are available in your LD_LIBRARY_PATH
(or equivalent). Note that JOGL favors the spec lib names for it's lib name order:
  ES2: libGLESv2.so.2, libGLESv2.so, GLES20, GLESv2_CM
  EGL: libEGL.so.1, libEGL.so, EGL

To utilize native ES2 on desktop (See TestGLProfile02NEWT and TestGearsES2NEWT)
you have to request the actual profile 'GLES2' otherwise
a request for e.g. GL2ES2 will utilize the highest common desktop profile.

<...
        if(!GLProfile.isAvailable(GLProfile.GLES2)) {
            System.out.println("GLProfile GLES2 n/a");
            return;
        }
        GLCapabilities caps = new GLCapabilities(GLProfile.get(GLProfile.GLES2));
