This is split from I4431882 to make that easier to review. This just
moves existing code around. It should not make any difference.

This is split from I4431882 to make that much easier to review.
Additional changes:
* Remove plural "s" from setRevisionPreviewHighlight
* Add "All" to removeAllRevisionPreviewHighlights
* Merge two methods into a single enableRevisionPreviewHighlights

This does the same as before, just in one single loop instead of so
many different steps.
The way the loop counts is odd. Why are the numbers returned by
getOldestVisibleRevisionIndex and getNewestVisibleRevisionIndex
off by one? I tried to make this more visible in the code without
touching it.

The extra "div.…" doesn't make the selectors more specific or
anything. The class name alone is unique. This makes the code
simpler, less brittle, and potentially even faster.

This code is updating the position and length of the yellow/blue
horizontal lines in the middle of the slider, left/right to the
yellow/blue circles.
1. setSliderLineCSS is called two times. A lot of the code before
is identical. Move all code that is identical into setSliderLineCSS.
2. The two single-use methods are very short now. Nothing but a
single function call. Merge the two calls into a single method.
Notice that `-0.5 * this.revisionWidth` is the same as
`-this.revisionWidth / 2`. I was able to make one disappear by
slowly transforming the code. It still does the same as before.

Storing a new entry in the browser history is the normal, default
thing to do. The only exception is on initialization, when the slider
is initialized from the browser history.
I hope this makes the code a little easier to read.

This click handler is assigned to many different elements. Not all
of them can be used as a source for a data-pos="…" attribute. But a
lot can.
Again, this patch alone will not actually fix T352169. But it will
improve the situation a lot, according to my local tests. Many of
the clicks will start to work fine on RTL wikis because the
problematic pixel-based getRevisionPositionFromLeftOffset
calculations are not used any more.
Steps to reproduce: Go to a RTL page with a very long history, e.g.
https://he.wikipedia.org/wiki/Special:Diff/38031767?uselang=he
Click on one of the gray bars in the right half of the slider. This
will not work, i.e. the slider will not move to this position but
to a totally different one. This is the bug described in T352169.
I noticed that a browser zoom other than 100% can cause many more
problems that are unrelated to this patch. Please test with 100%.

This updates the code a little bit to be closer to the current
version of https://github.com/othree/jquery.rtl-scroll-type
without actually changing anything (for now).
I tried copy-pasting the current version to see if that helps with
T352169, but it doesn't make a difference.
The only actual change is that the dummy element is removed when
it's not needed any more.

I have seen this getting fed with fractional numbers like
38.9994375. This apparently happens when specific browser zooms
are used, e.g. 110% in Google Chrome. There is a lot of code that
expects this to be an integer number and stops working entirely
when it isn't.
I'm also updating two related comparisons to not be so extremely
specific any more. This probably doesn't make a difference any more
with the fix above, but can't hurt.
This patch doesn't solve T352169, but is one more puzzle piece on
the way to solve it.

The version numbers mentioned in the comment are from the V8 engine.
The last Google Chrome version to use a 5.x version of the V8 engine
was Google Chrome version 59. That was 8 years ago. See T168299.
Our official support matrix asks for 3 years.
https://www.mediawiki.org/wiki/Compatibility#Browser_support_matrix
Notice how there is no version number in the code despite the comment
explaining that it shouldn't be used in later versions.
According to my local tests this is not a full fix for T352169, but
notably improves the situation. I can still see the bad behavior
described in T352169, but only in a narrow region on the right side
of the slider. Removing the obsolete browser detection is necessary
to unblock further investigation.
Making the dummy text a bit longer also makes an actual difference.
To keep this patch as minimal as possible all I do is to add a single
character.

The method is only called from two places, and both do very similar
things before the call. This duplication can be merged.
One notable difference is that .scrollLeft() was possibly called
twice before. The first call was pointless anyway. The argument for
.scrollLeft() is absolute, not relative.
This code cleanup is motivated by T352169, but doesn't solve it.

This was almost the exact same code, with very few differences (e.g.
different CSS classes, and different icons).
Another change in the same file is the removal of an extra
`!== undefined` check. This is impossible. I can't tell why this was
there. Maybe an artifact from when this was developed?

The latest update of 'svgo' dependency includes three optimizations on
converting path commands, which
- improves closing paths and how we determine if to use absolute or
relative commands.
- round arc or convert to lines based on the geometric sagitta
- convert cubic Bézier curves to quadratic Bézier curves where possible
Also unifiying npm command to qua standard notation `minify:svg`.

Notable:
* Arrays shouldn't be initialized like this. Instances will actually
share the same array object. Luckily this was dead code anyway
because it's re-done in the constructor.
* $timeOffset is already guaranteed to be an int.

This utility method doesn't really belong here. This does at least
reduce the surface area. Now it's only a single method instead of
two.

Turns out we can run into this failure situation even if everything
goes according to plan. It is possible to click just one pixel outside
of the valid range, e.g. on the very right corner right next to the
last bar. This is supposed to not do anything anyway, and correctly
doesn't do anything from the user's perspective. But it shows up as a
failure in the JavaScript console.
