Bug 1096 - Expose EGL to public: com.jogamp.opengl.egl.EGL ; EGLDrawableFactory: Validate static EGL func-ptr, probe EGL/ES2 first
- Move EGL to public package jogamp.opengl.egl.EGL -> com.jogamp.opengl.egl.EGL - EGLDrawableFactory - Validate static EGL func-ptr against EGL/ES2, ignoring EGL/[ES|GL] collisions w/ diff. native EGL implementations due to static EGL usage. - Probe EGL/ES2 first
