| Short Description | Pixel offset to use when drawing ULA or LoRes Layer. |
bits 7-0 = X Offset (0-255) (Reset to 0 after a reset)
ULA screen at this moment scrolls horizontally only by whole "characters" (by multiples of 8 pixels), the low 3 bits of offset value are ignored (as of core 2.00.26, may get modified/updated in later cores to scroll per single pixel also horizontally).
LoRes scrolls in "half-pixels" at the same resolution and smoothness as Layer 2.
