Respect the scale factor of container

[utilmind]

This is the fix for issue described several years ago in #625

To reproduce this issue, just scale the container of the Bootstrap Slider with CSS, set transform: scale(N), where N is different than 1 (increase or decrease size of the container and its entire content).

Also updated _toPercentage() method now has some size & speed optimizations.

When will this correction be adopted?

@ae-gladkikh I unfortunately do not have time to maintain this project. If you or anyone you know would like to maintain the package, I would be happy to add you/them as a maintainer!

@seiyria, Add me as maintainer. I don't have time too, but I can do a code review and approve good improvements. Still better than nothing!

[utilmind]

@seiyria Actually I just saw invitation. Thanks for inviting! Accepted.

[seiyria]

You're welcome @utilmind - thank you for offering to help out! We really appreciate it!

Figuring out failed tests, reading rules...

Anyway going to approve this improvement. It was successfully used in multiple projects during last 2 years.
Just couple of demos (both have no issues with scale factor on page):

1. https://utilmind.com/demos/2022/emotion-picker/
2. https://pro-pursuit.com/

UPD. Still can't build this project on my local environment. But determined to figure everything out and finally make a new release.

[utilmind]

Sorry, I still can't figure out how to pass the tests or how to modify them with my existing privileges (I don't have access to Netlify).

Although I have successfully built the package on my local environment with some changes. I had to stop using Grunt and Jasmine and it's probably not good... Probably the only option to me is to maintain the fork in the future, although it will be w/o tests anyway...

UPD. I will do more attempts later... Not sure whether I'm able to fix something on Netlify...

[utilmind]

Ok, was able to pass checks after upgrading NPM version, but build preview seems not good... Digging further...

[utilmind]

Yay!

When will this correction be adopted?

@ae-gladkikh Done. Please test it and let me know if you will have any issues.
(This is my first merge here, so despite I hope that everything will be fine, issues are possible.)

[utilmind]

For some reason "dist" folder doesn't contain updated packages. I thought that Netlify supposed to build it automatically... :-/
I'll figure this out and update files in "dist" ASAP.

Good news, i will test ASAP

[utilmind]

@ae-gladkikh now really released, files in "dist" folder updated.

(It turns out that it's not fully automated, the script that prepares the release should be run manually. Anyway, it's ready now.)
