The VSprite positions are defined in (y,x) order to make sorting sorting easier, since (y,x) as a long Longint.

BorderLine is the one-dimensional logical OR of all the VSprite bits, used for fast collision detection of edge

PlanePick flag: set bit selects a plane from image, clear bit selects use of shadow mask for that plane OnOff flag: if using shadow mask to fill plane, this bit (corresponding to bit in planePick) describes whether to fill with 0's or 1's

There are two uses for these flags:
