Only load extension entry points if the extension is supported. From the eglGetProcAddress manpage: "A non-NULL return value does not guarantee that an extension function is actually supported at runtime. The client must also make a corresponding query, such as glGetString(GL_EXTENSIONS) for OpenGL and OpenGL ES extensions [...] to determine if a function is supported by EGL or a specific client API context." This required moving extension initialization from OpenGLFunctions into OpenGLFunctionsBase.
