Ensured a settling delay is permitted before an NTSC/PAL decision is made. To avoid false switches just due to startup.

Attempted a hardware-correct implementation of missile-to-player latching. This completes the last of the **knowing** inaccuracies. The rest are as-of-yet unwitting.

Moved to the maximum possibly required queue length of 4. Though the emulated 2600 should never need more than 2 slots as per the current calling pattern, it's not a contractual guarantee.

Ensured the missiles and ball don't attempt to enqueue. Because I don't think they're supposed to.

Added a single-slot queue for player objects to defer drawing, thereby deferring pixel lookup. Which I think is correct. Though more slots might be needed.

Missile to player lock is supposed to be a toggle; also factored out the commonalities of missile and ball drawing.

In C++, I think the implicit cast to bool negates the need for any manual collapsing?
