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