// This file handles the External Frame Buffer (XFB). The XFB is a storage point when the picture is resized
// by the system to the correct display format for output to the TV. In most cases its function can be
// supplemented by the equivalent adjustments in glScissor and glViewport (or their DirectX equivalents). But
// for some homebrew games these functions are necessary because the homebrew game communicate directly with
// them.
