,/* Screen wobbling and Fine horizontal hardware scroll */
When R3l decreases by 1 (and if >2), the screen is shifted to the right by 8 mode2 pixels.
The shift is not instantaneous but follows a logarithmic attenuation over across several raster lines. This property can be used to get even finer horizontal control by modyfying R2/R3 on each raster line.
