Three endpoint gaps, found building the Descent 3 score overlay - the boxed
place|score field the original games drew over the callsign:
plasma box <x> <y> <w> <h> draws an outlined box with a blanked interior, the
overlay chrome, as one ESC P graphics write. The wire addresses whole bytes
horizontally, so the write covers the byte-aligned span containing the box and
clears span pixels outside it; documented, with 8-px alignment the advice.
Boxes queue FIFO with rows.
plasma text gains an explicit font: a third numeric token after the position,
with text still following, so `plasma text 2 2 7` still displays "7". Auto-fit
picks the font by LENGTH - short text always rendered large, and a "1" that
must fit a 12-px box simply could not be sent before. ResolvePosText
generalizes the legacy Score-font special case: 0 = auto, nonzero honored.
Text coalescing is now per position. The global rule - any queued text
superseded every other queued text - meant the documented two-field layout
(callsign top, score bottom) could not survive its own send burst: the second
field silently ate the first whenever both were queued. A newer text now
replaces only a queued text at the same (x,y).
15 new tests; 472 pass.
