Isabelle-specific implementation of quasi-abstract markup elements -- back to module arrangement before d83797ef0d2d;

prefer strict error;

quasi-abstract module Rendering, with Isabelle-specific implementation;

added convenience actions isabelle.increase-font-size and isabelle.decrease-font-size;

eval PDF_VIEWER/DVI_VIEWER command line, which allows additional quotes for program name, for example;

retain hidden_color (i.e. transparent white) instead of replacing it by semantic text color, to make control symbols more hidden and avoid "dirty" lines with some fonts;

prefer buffer_edit combinator over Java-style boilerplate;

more robust font for control symbols, to ensure these obscure codepoints are properly rendered;

tuned symbol groups;

tuned -- Symbol.groups already sorted;

more robust default font -- user might have switched jEdit TextArea to another font that lacks glyphs;

added option jedit_symbols_search_limit;

avoid empty tooltip;

tuned symbol groups;

special handling of control symbols in Symbols dockable; less obscure Scala names;

recovered some tooltip wrapping from e2762f962042, with multi-line support via HTML.encode;

avoid showing semantic aspects of Unicode -- Isabelle/Scala merely (ab)uses the low-level rendering model (codepoint + font);

more NEWS/CONTRIBUTORS;

improved editing support for control styles; separate module for Isabelle actions;

added ISABELLE_PLATFORM_FAMILY;
