/*
 * 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.
