bflatasticandClaude Opus 5.5 64891c1a2e Fix #234: EPS files from the reference app open ...

EPS files the reference app saves (its procsets in the prolog, a binary header with a TIFF
preview) now open as editable art instead of failing with "undefinedresource in Generic". When
their PostScript still can't be read, the palette preview they carry is placed with the usual
warning instead of the file being refused.

Root cause: five interpreter gaps and one preview format. The Generic and Category resource
categories didn't exist, so categories couldn't be made from Generic (now Category holds the
standard categories, defineresource in Category makes new ones, undefineresource is added);
clipsave/cliprestore were unknown (now a clip stack in the graphics state); systemdict's
languagelevel was the operator, not the integer 3; getinterval copied arrays and strings
instead of sharing their storage, so astore into a subarray was lost (arrays and strings are
now views into shared storage, and readstring/readline return the part they fill); and
resourceforall was unknown (now enumerates matching names with * ? \ templates). The preview
is an 8-bit palette TIFF with an alpha sample, which the image crate can't decode: a small
bounds-checked reader handles that layout (either byte order, any strips).
