- improve mandelbrot shell script
- add fractal.c: a fractal generator and navigator that can
be used as a terminal stress test.
- add fractal-mode for easy fractal navigation and zooming
with key bindings.
- try it out with C-h m SP / SP / SP ...
- add 8K color modes and 64-bit QETermStyle values
- add 64-bit buffer style support
- reduce colored character system used in syntax handlers to 8-bit style
and 24-bit code point
- use QETermStyle type instead of int wherever a composite style is used
- force color system used by the terminal with environment variables:
USE_16_COLORS=1, USE_256_COLORS=1 or USE_TRUE_COLORS=1
- rename font styles QE_STYLE_xxx to QE_FONT_STYLE_xxx
- rename font family QE_FAMILY_xxx to QE_FONT_FAMILY_xxx
- improve tests/16colors.pl: display bold italics combination
- improve tests/color-spaces.pl: compare true color and palette dumps
- add colortest target in Makefile to produce various color patterns
- add various utilities for color escape sequence testing:
tests/16colors.pl
tests/256colors2.pl
tests/color-spaces.pl
tests/truecolors.sh
tests/xterm-colortest.sh
tests/xterm-colour-chart.py
- use colored code-points only for syntax highlighting
- use QETermStyle and QEStyleDef internally
- convert to TTYChar attributes only for text terminal output.
- remove most CHAR_MASK and STYLE_SHIFT handling
- pass QETermStyle array to get_colorized_line mode handlers
- pass QETermStyle array to isearch_colorize_matches
- remove combine_static_colorized_line
- move color matching functions to util.c
- rename get_tty_color as qe_map_color
- improve local variable naming consistency:
DisplayState *ds, QEStyleDef *stp, QEStyleDef styledef.
* use charset probing functions to detect ucs2 and ucs4 charsets in files
without a BOM (byte order mark)
* add test files for multibyte charsets in tests directory
* filter control characters and non BMP1 code points
* new mode specific modeline
* do not space out single width glyphs (not very readable)
* eb_get_char_offset: add validation on offset argument
* eb_get_char_offset: align offset argument on character boundary
