25 * Command to load a splash screen to the VFDs.
26 * NOTE that this will be controlled by a key combination when
27 * the keyboard stuff works. For now the user has to enter a
28 * bitmap number (only VFD_TEST_LOGO is supported now - 16.10.2002).
29 * Added VFD_REMOTE_LOGO (same as VFD_TEST_LOGO but a different color)
30 * on 20.10.2002.
31 *
32 * This rather crudely requires that each bitmap be included as a
33 * header file.
