COMMENT !
//
// This option causes DrvCreateDeviceBitmap to always succeed.
// It maps all device bitmaps to screen 0,0. Thus we have an "infinite"
// supply of offscreen memory.

// It is not necessary to set USE_ASM = 0 for this flag.

;/* ================== NULL driver flags ================================
COMMENT !
Once NULL driver capabilities are enabled, they are turned on and off by moving the pointer to (0,0) which toggles do_flag on and off. See DrvMovePointer().
These allow us to selectively 'short circuit' certain parts of the driver. 0 Normal operation. 1 Immediately return TRUE.
It is not necessary to set USE_ASM = 0 for the null driver flags.
