[Pager] Support offscreenPageLimit

[lsuski]

Is your feature request related to a problem? Please describe.
Currently to achieve with HorizontalPager displaying partially next/previous page we have to define contentPaddings. However it is not always desirable. With ViewPager2 we can manipulate page in page transformer (e.g set transalationX) along with offscreenPageLimit = 1

Describe the solution you'd like
HorizontalPager and VerticalPager should support offscreenPageLimit the same as ViewPager2 does

Please use the bug above to track that. Once we have that in lazy lists we will add this functionality in the new Pager we are working on for Compose UI

@andkulikov The linked issue is fixed since October 17. By "new Pager for Compose UI", do you mean a different component than this library's pager? If yes, is there any information on a roadmap for this component? If no, is there any information when Accompanist's pager will take up the new LazyList offscreen capacity?

[andkulikov]

@mtotschnig hey, we are currently designing a new Pager component which will live right in compose.foundation and it will be a replacement for Accompanist's Pager. We are planning to provide an experimental version of this component in Compose 1.4. It will have an api for setting offscreenPageLimit

@andkulikov in 2024, how can we set offscreenpagelimit ? seems like it has been removed

[andkulikov]

Accompanist Pager is deprecated, please use a HorizontalPager available in the main compose:foundation library. This component has a param for this functionality

thank you @andkulikov, you helped me persevere, for those who are lost :

It has been renamed : beyondBoundsPageCount
