* New Definition class FontDef for font selecting commands defined by \font; modify \font accordingly * Rename parameter type FontToken to FontDef for cs explicitly defined by \font (ie FontDef); update font info accessors which use this token ( \fontdimen, \fontname, \hyphenchar, \skewchar) * Update \meaning to recognize new FontDef font commands * Update \the to recognize FontDef commands defined by \font and process them correctly; remove badly named Register Parameter type which was only used for \the * Moved decodeMathChar to Package.pm, updating it to more correctly decode mathcodes and recognize the \fam font family for the class=7 special case, and more reliably lookup the codepoint in the encoding appropriate to the selected font; Initialize \fam (font_family) when entering math mode, and use decodeMathChar when digesting simple tokens in math. * Note that \mit doesn't REQUIRE math, but ony has effect in math (sets \fam) * Consistent use of font decoding makes apparent misuse of T_OTHER when reconstructing duals in siunitx * Fix mangled renesting of if/else * \cal also does not require math and does nothing in text * Add test case for plain style font manipulations * Improve decoding of font filenames into family/series/shape and IMPORTANTLY encoding; rearrange lists * Update FontMap to provide options for alphanumerics to remain ASCII in math, but with (semantic) font styling which is post-processed as before; BUT while allowing those same chars to map to Unicode when in text mode, since these cases are often rather exotic fonts not easily covered by pure CSS. * Make FontDecode in math keep alphanumerics in math as ASCII w/font change, but unicode in text, Now returns BOTH the glyph and font; corresponding changes to decodeMathChar * Update all callers of FontDecode * Make \cal return a Box so that it can revert * Enhance and correct plain fonts test cases * Code cleanup suggested by D.Ginev
