+ * 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.
