7aec32ced5 Update demo to leverage BG1 scanline support 2023-03-11 03:42:23 -06:00
Lucas Scharenbroich
9021ee4506 WIP of BG1 scanline effects 
A static BG1 is stable with BG0 offset values.  A seam in BG1
needs to be closed up by taking into account the BG1XOrigin value
when setting the :shift_value.

Also, several routines were hard-coded for the scanline case.  These
hanges need to be reverted and properly parametereized.
