add api to ewekbit/webview to be able to register "callbacks" that disable
scrolling (of a parent) in the horizontal or vertical axis. webview doesn't then
ened to know about elm at all. if a callback is registered and it wants to
disable or re-enable scrolling in a direction, it calls that callback. it is
the callbacks' job to "do whatever is needed". in this case you have some glue
code that provides the callback, registers with webview and inside the callback
it provides.. it calls the "disable scrolling in axis x/y on parent" code. :)
presto. problem solved. :) you just need the glue bit.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
