FR: Scroll to position

[Frenzie]

One I really miss is "scroll here to top/bottom".
I read lots of PDFs, zoomed to content width. Now sometimes there is an image or diagram that straddles the page, and I'd like to draw a horizontal line at the top of the image, and then vertically up to the top rim of the screen, meaning: move this position to the top. Likewise with moving the bottom of the image to the bottom of the screen.
(And being left-handed, those horizontal parts would be right-to-left.)

Any progress here?

I've been using the on-release scrolling feature activated via panning for this scenario. With eb34fbb setting the position is supported, so it's mostly the gesture-like activation that is missing.
