Draw the laser like the ball's aim band, and let the two be compared

TUNE.beamBand flips between the two looks live from the T panel. 1, the new
default, draws the laser the way the BALL's aim trajectory is drawn: a path down
the lane whose width comes from each point's own projection scale, so it narrows
into the distance like everything else on the court, with a shadow on the lawn to
pin it there. 0 is the solid widening cone.

The cone was a true projection, which is why it was not obviously wrong to me --
but it GROWS in world width, so on screen it opens out while the court recedes,
and the eye reads that as a shape stuck to the screen rather than a plane lying
in the world.

The kill follows whichever look is on, in both fireBeam and drawBeamCuts.
Otherwise the comparison would be a lie: a narrow band that deletes a cone-wide
crowd tells you nothing about how the narrow band plays. Measured down one lane,
the cone takes 9 of 9 and the band 5 of 9.
