* metafile: hold a placed pen width to what covers the frame Picture::place scaled a pen width by the fit with no upper bound, so a pen of 1e30 units made a renderer flatten round caps of that size. A placed pen is now at most twice the diagonal of the frame and the path together, which already covers the whole frame. Ported from storytold/wordcraft#5427. * metafile: one byte budget for items, EMF+ objects and clips; count clip regions when placing - Canvas::shade_shape returns when the canvas is full or the clip is empty, instead of sampling a tile that is then dropped. - EMF+ objects, the pieces of a continued object and the current and saved EMF+ clips count against the canvas's 256 MiB budget, in both directions: an object is not stored past what the canvas holds, and the canvas stops at what the objects hold. - A nested metafile held by an EMF+ image object is charged for what its items own (segments, pixels, text, clip rectangles; a shared tile or clip path once) rather than 128 bytes an item. - Picture::place charges each clip region it expands to the 500,000 element budget, for every kind of item, and expands a region once for the consecutive items that share it. Ported from storytold/deckcraft#1777, with its review comments addressed (the canvas checks include the held bytes; text and bitmap items are checked too; regions are matched by content, not by address). * metafile: a negative crop side pads the picture crop_window took each side as 0..1, so a negative side (a negative a:srcRect side in an Office file, or a picture fitted whole into a frame of another shape) was dropped and the picture was stretched over its frame. A side is now taken down to -100: the window starts before the source or ends past it, and Picture::fit places the source inside the frame at its own proportions. Ported from storytold/wordcraft#2027 (the -100 bound and the invariant test) and storytold/wordcraft#5206 (the padding test). * metafile: decode 8-bit text in the font's code page 8-bit text (WMF TEXTOUT and EXTTEXTOUT, EMF EXTTEXTOUTA and SMALLTEXTOUT) was decoded in Windows-1250, 1251 or 1252 only, and a double-byte character became a blank. - Greek, Turkish, Vietnamese, Hebrew, Arabic, Baltic and Thai character sets decode in their code pages (encoding_rs, already a workspace dependency). - Shift_JIS, UHC, GBK and Big5 pairs decode to their character, with the lead and trail ranges of each set; the character keeps the advances of both bytes. A lead byte without a trail byte is one undefined byte. - A WMF face name is read in the font's code page. - The Symbol font selected with DEFAULT_CHARSET keeps its bytes as symbol codes (U+F000 + code), as SYMBOL_CHARSET fonts do. Ported from storytold/wordcraft#5187 (the code pages, the double-byte ranges, the face name and the Symbol font) and storytold/deckcraft#792 (the Hebrew and Arabic tests). --------- Co-authored-by: Dmitrii Khlapov <19991457+dkhlapov@users.noreply.github.com> Co-authored-by: David Lin <woei66@gmail.com>
