this allows using the pagescroller for scrolling elements into view where the rect gets calculated somewhere else
Example: CodeMirror has the `cm.cursorCoords()` function that returns the rect of the textselection (or cursor coordinates)
this scrolls the cursor or text selection into view using tiddlywikis pagescroller:
`$tw.pageScroller.scrollIntoView(undefined, function() { return self.cm.cursorCoords(true,"window"); });`
* correct scrolling with tc-adjust-top-of-scroll
not multiplying `offset` with t causes jumps at the first animation steps, where the offset value is bigger than `endY - scrollPosition.y`
* correct scroll offset
The previous fix changed the scrolling behaviour such that it only
scrolled to the top of a tiddler if the tiddler was entirely offscreen.
It wasn’t entirely satisfactory because scrolling was prevented even if
only a few pixels of a tiddler are in view. This commit ensures that
the scroll does occur if less than 50 pixels of the target is in view
@aelocson here’s an alternative fix for #981, as discussed in
https://github.com/Jermolene/TiddlyWiki5/commit/691e5719a4ff74a04d389bd1

It does seem a lot nicer. It avoids the problem you raised, and also
avoids scrolling when a permalink is used.
I suspect that we’d need to make the hard-coded 50 pixels be
configurable.
"Plugins" are bundles of tiddlers managed as one, "modules" are
JavaScript tiddlers with a module type identifying when and how they
should be executed.
