+### RE-CUT: BT411_4.11.771.zip supersedes 767 (never distributed)
+Merged Cyd's glass-lamp-latency (per-frame lamp STATE sweep, glass only,
+BT_GLASS_LAMP_SWEEP=0 restores; #45 citation in his comment fixed to
+"field reports").  Smoke-tested: cockpit + all MFD panels un-regressed,
+no compositor artifacts.  SCOPE NOTE for testers: this fixes BUTTON/lamp
+responsiveness under load in all glass layouts INCLUDING separate
+windows; instrument-SURFACE refresh (needles/pages) still rides the
+throttled background gauge sweep and can lag on heavy missions -- the
+background-sweep starvation dig is the follow-up.  767 zip deleted.
