LoRes X Scroll Register

Number	TBRegisterNumber::$32
Readable	TBRegisterReadable::Yes
Writable	TBRegisterWritable::Yes
Short Description	ShortDesc::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.
