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

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

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

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

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

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

    41  * construction error will result in a panic.
