In 6309763 we added a new class called OGLUtilities that allows third-party libraries
such as JOGL to interact with the OpenGL-based Java 2D pipeline. (This API is
completely unsupported but is a hopefully temporary measure until we can support
a public API in a future release.)
We need to add a couple new methods to the OGLUtilities class to make it more useful,
specifically so that JOGL can interact properly with the GL_EXT_framebuffer_object
support that we added to the OGL pipeline in Mustang. This FBO support will signicantly
improve performance of applications that make use of JOGL's GLJPanel class.
