Ts, Tc, Tw, Tz, TL and Tr took their first operand, Tf its first two,
and " its first two numbers. The renderer takes the operands immediately
before the operator and ignores any surplus before them, so surplus
operands (`1 50 Ts`) moved the interpreter's glyph boxes away from the
text the page shows: removal and verification missed it.
Each of them now reads its trailing operands.
