Everything is fine after all

Previous WB tests are incorrect, if no ECS Denise, last visible line is always 310, not 311. (copper waits for start of line 311 and then zeroes BPLCON0 = line 311 is blank).

If ECS Denise (or AGA): last visible line is really 311. Complete WB overscan is visible.

(Why this difference? I don't know). EDIT: "difference" as in different copper lists created by OS3.1 depending on Denise type. Hardware limits of course are still the same.

Line 312 is always blanked line if non-A1000 Agnus and this is outside of WB overscan area. (if long field mode)
