Subject: [PATCH] #149: [glassperf] VERIFIED in the 2-node render harness
 (correcting 9e78d1c's premature claim)

9e78d1c said 'smoke-tested: lines live' -- that run never entered the render
loop and printed nothing.  This run did: 54 [glassperf] lines, e.g.

  ticks=16 tickMs=256.9 | Heat MFD 24.8 | Engineering 20.6 | Comm 18.7 |
  LeftW 20.6 | RightW 22.8 | Secondary/Radar 67.9 | ...

First finding, already: the synchronous panel sweep costs ~257ms/second even
on the DEV box (25% tax, hidden in headroom), and Secondary/Radar -- the
ROTATED portrait blit -- is the most expensive window.  Oracle's machine
paying 4-8x that through his driver is now a quantified hypothesis, not a
guess.  Optimization targets regardless of his verdict: dirty-gated repaints,
non-HALFTONE unscaled blits, cheaper rotation.
