 * SCR_DEV.H - Screen Device codes
 * The user should modify this file to have different codes for all
 * supported devices. The open routine for the device should initialize
 * SCR_PHYS_DEV and SCR_VIRT_DEV in the SCREEN object to be one
 * of the following codes. The order is not important.
 * They need only be reasonably sequential (there can be "holes")
 * and smaller than 256.
 *
 * SCR_PHYS_DEV selects the UNIX physical device which is opened
 * (and closed). SCR_VIRT_DEV selects a class type that determines how
 * each Shapes class is implemented for that particular device.
 * Note that the UNIX device can be different than the implementation.
 * For example, the cg4 overlay planes open UNIX device CG4
 * (SCR_PHYS_DEV = SCR_DEV_CG4) but use the bw2 class type to access
 * the bit planes (SCR_VIRT_DEV = SCR_DEV_BW2).
