In the legacy format, `Tr` sets the rendering mode of the type that follows. Section 5.7 of the version 7 specification says that modes 4 to 7 make the text object a mask: 4, 5 and 6 also fill, stroke, or fill and stroke it, and 7 paints nothing. Sections 15.3.2 and 15.4.5.1 add that these modes are used in pattern definitions, and the reader does not read type in a pattern. The reader painted 4 to 6 like 0 to 2 and never clipped, so the art a text mask clips showed whole. A text object with characters in modes 4 to 7 is now a clipping path of its clipping group (`q` ... `Q`, or the layer), as a path painted with `W` is, and the whole object is the mask. Beside other clipping paths it nests as they do, and the mode lasts into later text objects. Area type with linked areas (threaded frames, also when the reader's limits keep one frame), and type in wraparound text or in a compound path, a group inside them included, doesn't clip, with a warning. A `Tr` operand that is not a whole number from 0 to 9 now leaves the mode as it was; before, 4.5 read as 4 and -4 hid the type. The new warning and the reader's warning about linked type areas left out get rows in every catalog.
