* lisp/proced.el (proced-grammar-alist): Change the justify
value of the start attribute to 'left' instead of a fixed
value of 6.  (Bug#64752)
(proced-format-start): Adjust the doc string.

* lisp/proced.el (proced-mode): Force the header-line to scale
according to 'text-scale-adjust'.
(proced-header-line): Use width of the header-line's face's
characters as align-to units, not the width of the frame's
default face's font.  (Bug#64752)

* src/xdisp.c (calc_pixel_width_or_height): Use font's
average_width or space_width, not max_width, as the correct
measure of the font's width.  This is consistent with the rest of
the display engine.

Preserve the window position for windows which display a proced
buffer, but are not the selected window when a proced buffer is
updated.  Previously, the window position would be set to the
start of the buffer when a proced buffer was updated and it was
not displayed in the selected window.

Similarly, preserve the position in proced buffers which are not
displayed in any window by setting
'switch-to-buffer-preserve-window-point' to nil in proced buffers.

* lisp/proced.el (proced-auto-update-timer): Only update a given
proced buffer if it is displayed in a window.
(proced-update): Set the window position if the proced buffer is
displayed in a window.
(proced--position-info, proced--determine-pos): New Functions.
(proced-mode): Set 'switch-to-buffer-preserve-window-point' to
nil in proced buffers.
* test/lisp/proced-tests.el
(proced-update-preserves-pid-at-point-test): New test.

Make proced-update preserve refinements by creating a new buffer local
variable proced-refinements which stores information about the current
refinements and is used by proced-update to further refine
proced-process-alist in the case it is non-nil.  The result is that
refinements are not immediately cleared when a proced buffer is
updated with proced-auto-update-flag non-nil.  proced-revert
maintains its current behaviour of clearing any active refinements.

* lisp/proced.el (proced-refinements): New buffer local variable
which tracks the current refinements.
(proced-refine): Set 'proced-refinements' variable and defer setting of
'proced-process-alist' to 'proced-update'.
(proced-update): Take into account 'proced-refinements' when setting
'proced-process-alist'.
(proced-revert): Set 'proced-refinements' to nil prior to calling
'proced-update'.

* lisp/proced.el (proced-low-memory-usage-threshold)
(proced-medium-memory-usage-threshold, proced-run-status-code)
(proced-interruptible-sleep-status-code)
(proced-uninterruptible-sleep-status-code, proced-executable): Fix
doc strings.
(proced-format-time): Simplify the format, to avoid bogus warnings
from the byte-compiler.

* etc/NEWS: Move Proced entries to one place and fix their
wording.

Add a new custom variable proced-enable-color-flag which when set to a
non-nil value (defaults to nil), will prompt some format functions to
furnish their respective process attributes with colors and effects in
order to make them easier to distinguish and highlight possible issues
(e.g. high memory usage), in a manner similar to htop.

In particular, the current Emacs process id is highlighted purple in
both the process id and parent process id columns, session leaders
have their process ids underlined, larger memory sizes for rss
are highlighted in darker shades of orange, and the first word in the
args property (the executable) is highlighted in blue.

* lisp/proced.el (proced-grammar-alist): Update to use the new format
functions.
(proced-low-memory-usage-threshold): New custom variable to determine
whether a value represents 'low' memory usage, used only in
proced-format-memory for coloring.
(proced-medium-memory-usage-threshold): New custom variable to
determine whether a value represents 'medium' memory usage, used only
in proced-format-memory for coloring.
(proced-enable-color-flag): New custom variable to toggle coloring.
(proced-run-status-code, proced-interruptible-sleep-status-code)
(proced-uninterruptible-sleep-status-code, proced-executable)
(proced-executable, proced-memory-gb, proced-memory-mb)
(proced-memory-default, proced-pid, proced-ppid, proced-pgrp)
(proced-sess, proced-cpu, proced-mem, proced-user, proced-time-colon):
New faces.
(proced-format-time): Edit function to color colons using
proced-time-colon.
(proced-format-args): Edit function to color executables using
proced-executable.
(proced-format-state): New function to color states.
(proced-format-pid): New function to color process ids.
(proced-format-ppid): New function to color parent process ids.
(proced-format-pgrp): New function to color process group ids.
(proced-format-sess): New function to color process session leader
ids.
(proced-format-cpu): New function to color cpu utilization.
(proced-format-mem): New function to color memory utilization.
(proced-format-user): New function to color the user a process
belongs to.
