Option for increasing the number of tiles buffered at the border of the viewport

While zooming out a grey border gets visible at the border of the viewport. See image below:

It would be nice to have an option to increase the number of tiles that get buffered.
Maybe something similar to the keepbuffer of leaflet

@msschl keepbuffer is not about preloading tiles, it's about keeping already loaded ones. In case of GL JS, we already do a good job of cashing tiles for rendering, but we can't afford preloading tiles around the screen because it will affect performance severely for a very minor benefit. Also consider that you would need to preload a lot of tiles to accommodate rapidly zooming out. There's an alternative proposed in #2826 which might be better suited to address this.

You're right. I got something mixed up. #2826 is what I'm looking for. Thanks though 👍🏽
