Mouse gestures
@fusionfuture et al. convinced me that mouse gesture support for KWin/Plasma is worth working on. Following some earlier brainstorming, I now have a prototype with just stroke recognition working. Before I go deep down some rabbit hole that's not suitable for upstreaming, it seems sensible to get feedback first. Then aim for carving out MR-size chunks to go into kwin, plasma-desktop, or wherever the heck is the right location for all the various parts.
Let's start with that and use comment threads for various topics.
Note that mouse gestures seem quite different from touch gestures, both in user inputs and resulting function. I figure there isn't all that much overlap between these despite both being called "gestures". Hence "stroke recognition" (or when associated with actions, "stroke actions") seems like a less ambiguous term.
