 * TEglEndpointWrap is a simple class that presents all of the EGL endpoint

 * extension functions without the user needing to perform an eglGetProcAddress()

 * to obtain the function pointer. Each endpoint member function takes the same

 * arguments as the EGL functions and returns the same types. After before first

 * use, you should check the Error() function to ensure that all function pointers

 * were resolved. Trying to use one of the endpoint functions in the event of a

 * construction error will result in a panic.
