Added: Initial revision of button interacted slider

[dvdvideo1234]

I see people really tend to like this feature, so I am sharing the code of this panel here ;)

[dvdvideo1234]

It will inherit DSizeToContents, then attach slider and buttons ( below ) to it. Buttons can used to interact with the slider:

Hi, a Button-interacted slider

The idea is for the user to interact with slider faster. It requites one action to snap to 45 degrees for example and can be customized for the buttons to do different actions:

You might want to rework your coding style according to https://github.com/Facepunch/garrysmod/blob/master/CONTRIBUTING.md, though.

@Grocel

Yes, sir, sadly I do not really have time during the day of work and pretty tired to do in the evening. Finished the final revision though. Works like a charm!

[dvdvideo1234]

Done. Fixed also Set(Tall/Wide) when passing only panel size

Hi, @Grocel @robotboy655

I wonder is it worth it to do some factorization:

Or this panel is fine as it is ?

[Grocel]

@dvdvideo1234 What's the status of this PR? Did you take a look into the coding style the game base file requires? These short variable names BDX and BDY are not good variable names in this project.

Other stuff I noticed is: Statements like these:

if(iSiz <= 0) then return 0 end

Should look like these:

if ( iSiz <= 0 ) then
    return 0
end

Please take a look at: https://github.com/Facepunch/garrysmod/blob/master/CONTRIBUTING.md

[dvdvideo1234]

Done.. I think I got them all but if some are remaining pls point them out

[Grocel]

The ifs are still off, mind the space between brackets, also those before and after them.

[dvdvideo1234]

Should be good now

[Grocel]

Looks much better now. I am not sure what Rubat thinks of this, though.
