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.

a70412211c Simplify and specialize the even/odd patching
Allows the odd case to be slightly more efficient and the
code is cleaned up by not having to handle both even and odd
alignment cases at multiple points.

536959619f Refine the horizontal dispatch
Find small optimizations to improve the average performance of the
blitter, especially in the odd-aligned case.

 - Odd-aligned PEA exit is 2 cycles faster per line
 - Odd-aligned JMP exit is 2 cycles faster per line
 - Odd-aligned LDA exit is 6 cycles faster (eliminated long store)
 - Merged setting the entry opcode and offset to convert 2 8-bit
   store into a single 16-bit store (save 6 cycles per line)
 - Load and save the full word for the high bytes. Cost 2 cycles
   but enabled the 6 cycles saved for the LDA case.
