Swiper thumbs => swiper-wrapper padding

[denny7]

Hello!
I would like to add horizontal and vertical padding to swiper-wrapper so I can add some background, rounded corners, etc., for my thumbnails. I don't have any problem with setting vertical padding, but when I add horizontal padding, swiper-wrapper doesn't include it in calculation for transform and it causes cutting my last thumb. I tried to wrap all slides in custom element but it seems Swiper ignores it. When swiper thumbs is smaller than viewport width I don't have any problem. What is more, I don't add padding directly to swiper-thumbs because I need this background to fit width of its inners children (when thumbs width is less than viewport width, background should be smaller than viewport width).
