new routines `mirror_start()`, `mirror_outfile()` & limit substitutions on Unix to backslash (Windows remains the same); restrict "borderwidth", "textgap", "vwhitesp", "whitesp" < 100 CODEONE: fix `ceilf()` -> `C1_MULT_CEIL()` in FAST_MODE encodation (improves/changes some encodation) composite: preserve `gs1_verify()` warning using `warn_level` hack; fix wrong name `zint_dbar_omnstk_set_height()` -> `zint_dbar_stk_set_height()`; use new `zint_micropdf_variant()` & `zint_micropdf_expand()` routines (see below) MICROPDF417: move variant determination into new shareable routine `zint_micropdf_variant()` & expansion into `zint_micropdf_expand()` qzint: add helper methods `setbordertypevalue()`, `encodedinputmode()`, `encodedoutputoptions()`, `ecivaluetoeciindex()` and `eciindextoecivalue()` dbar: for performance pre-calculate `combins()` as array coverage: add `malloc()`-type failure testing to AZTEC, CONTENT_SEGS, MEMORY_FILE, raster, Reed-Solomon & vector; numerous changes to remove unused code and test more branches common: add `isxdigit()` general: various code fiddlings manual: add char names to sequence and batch format char tables; mention long options can be shortened (& use "--compliantheight" -> "--compliant"); expand mirror explanation & document substitutions in footnote; workaround xecjk putting space after double quote when quoting cjk chars & rejig input mode examples; workaround html alignment bug in table gs1-enabled symbologies by adding extra rh dashes to header cols; add "figure nn: " to txt image tags via sed: various other small fixes and rephrasings
