as suggested by @Explorer09. It's not really faster.

(Stupid me for forgetting to delete the line when changing code in commit 5c18866e )

Thank you @Explorer09 for the report!

The variable 'dot' in GraphMeterMode_draw now means "maximum number of
dots per value (column) in graph". The old meaning was "amount of value
that is to be represented by a dot" and was always a fraction. Due to
a limitation in floating point computing, if GRAPH_HEIGHT were not a
power of 2, then rounding errors will occur on numbers like (1.0/3).
(Currently GRAPH_HEIGHT is 4 and so no precision loss.) 'dot' was used
as a divisor, and it's "division by a reciprocal". We change that to
simple multiplication.

This allows the graph be rendered with a differ color scheme when user
changes the color scheme.

This patch colors the graph meter based on the items of the bar meter.
For example, if most of the CPU power is running on low-priority
processes, then blue will be shown on the graph columns. If most of the
CPU is running on kernel things, then the columns will be red, and so
on.

The algorithm in this patch is not final yet. Expect some bugs such as:
that some of the cells are colored gray while ideally they shouldn't.

Currently GRAPH_HEIGHT=4 . This prevents hard-coding the height of the graph meters, and allows user to change it at compile-time.

(It's still unchangeable in runtime yet. Can a Setup option be implemented for this thing?)

If the terminal has no font with braille characters we see... Nothing
useful. Use an ASCII blank at least, so we have an idea about what's
going on.

* Use MIN() and MAX() to make sure values are inside bounds. This should
  fix an issue where Meters were missing dots at the bottom.
* Remove variable 'level' and calculate on the fly.

With more dimensional arrays we have to define the array size. Use
one dimensional arrays to be more flexible.
Additionally this allows to shrink array size for ASCII.

Fixes building on case-insensitive filesystems where String.h gets confused with <string.h>.

Subject: [PATCH 1/8] Rename String to StringUtils

Kinda runs, but functionality from the original main loop
is still missing. Patience.

This is a work-in-progress, code is currently broken.
(Some actions, and notably, the header, are missing.)

Set up environment to move other meters.

(Patch by Dawid Gajownik)

See https://bugzilla.redhat.com/show_bug.cgi?id=987805 for details.
(thanks to Dawid Gajownik for the detailed analysis!)

Changes in object model: separate class objects to store vtable. Also, nicer UTF-8 display of big numbers.

* Performance improvements
* Support for splitting CPU meters into two or four columns
  (thanks to Wim Heirman)
* Switch from PLPA, which is now deprecated, to HWLOC.
* Bring back support for native Linux sched_setaffinity,
  so we don't have to use HWLOC where we don't need to.
* Support for typing in user names and column fields in selection panels.
