...
skip experimental 6th viewport that got forgotten
and limit max zoom to 7 (range 0-7) which is what looks good

Note how many cycles loop unrolling saves
...
+4 cycles one-time setup
ldx #8 ; 2 cyc for first 8
ldx #8 ; 2 cyc for second 8 (different shift behavior)
-5 cycles/iter to get bit now
lsr arg + 1 ; 5 cyc
rol arg ; 5 cyc
+10 cycles/iter to get the bit in a loop
dex ; 2 cyc
bne ; 2 cyc
4 cycles/iter for the loop
4 + (14 * 16) = 4 + 224 = 228
