Styles may be set directly or by themes. If no theme is specified in
`ZSH_HIGHLIGHT_THEME` the `default` theme will be loaded. Additional themes
may be layered on top (overriding previous theme's settings) by calling
`_zsh_highlight_load_theme`. `_zsh_highlight_load_theme` takes either an
absolute path to a theme file to load or a theme name. For a theme name the
base theme from the themes directory is loaded and then the extensions of the
theme that any active highlighter has are loaded. Names must not contain a `/`.
The `default` theme is a colorful theme that preserves the defaults the
highlighters originally had. The `error-only` theme is also available for
highlighting only syntax errors.
Some highlighters support additional configuration parameters; see each
highlighter's documentation for details and examples.

* Implement the `_zsh_highlight_highlighter_acme_paint` function.
This function does the actual syntax highlighting, by calling
`_zsh_highlight_add_highlight` with the start and end of the region to
be highlighted and the `ZSH_HIGHLIGHT_STYLES` key to use. Define the default
style for that key in the highlighter script outside of any function with
`: ${ZSH_HIGHLIGHT_STYLES[key]:=value}`, being sure to prefix
the key with your highlighter name and a colon. For example:
```zsh
: ${ZSH_HIGHLIGHT_STYLES[acme:aurora]:=fg=green}
be highlighted and the `ZSH_HIGHLIGHT_STYLES` key to use. The key should
be prefixed with your highlighter name and a colon

# Colorize the whole buffer with the 'aurora' style

These names are still supported for backwards compatibility;
however, support for them will be removed in a a future major or minor release (v0.x.0 or v1.0.0).
* Optionally extended the built-in themes in
`highlighters/${myhighlighter}/themes/${themename}`.
Define the theme's style for that key with `ZSH_HIGHLIGHT_STYLES[key]=value`,
being sure to prefix the key with your highlighter name and a colon. For
example:
ZSH_HIGHLIGHT_STYLES[myhighlighter:aurora]=fg=green
