Canvas images support efficient updating and refreshing. An image
specifier with ':type canvas' creates a canvas image. The canvas has an
associated writable pixel buffer. After changing the ':data' vector or
writing to the pixel buffer a call to 'canvas-refresh' redraws the
canvas image. See bug#80281.

Outline provides two search strategies to locate headings. If
`outline-search-function' is defined, it is used to find the headings.
Otherwise, `outline-regexp' is used. Reimplement `outline-occur' as
`outline-xref' using Xref and accepting a search function. This
supports both search strategies and ensures that the headings detected
by `outline-xref' match the Outline ones.

Convert simple function analyzers to use it.
* etc/NEWS: Announce it.
Many analyzers (those defined with
'elisp-scope-define-analyzer' and friends) are appropriate
for more than one function/macro. Before this commit, our
way of reusing an analyzer was to do this:
;; Define analyzer for `foo'
(elisp-scope-define-function-analyzer foo (...) ...)
;; Reuse it for `bar'
(put 'bar 'elisp-scope-analyzer #'elisp-scope--analyze-foo)
This isn't a good solution for users/packages that want to
reuse their custom analyzers, because it relies on too many
brittle internal implementation details.
This commit provides a nicer solution: we generalize the
analyzer-defining macros so they can take a list of symbols
and directly associated the defined analyzer with all of
the given symbols. So the above example is simplified to:
(elisp-scope-define-function-analyzer (foo bar) (...) ...)
* lisp/emacs-lisp/elisp-scope.el (elisp-scope-define-analyzer):
Accept either a symbol or a list of symbols, and register
the analyzer function for each symbol in the list (bug#81355).
(elisp-scope--define-function-analyzer)

via separate 'put' calls to use this new feature instead.
