		brechtUnsubmitted Done Inline Actions I guess this event is often redundant, and already handed through a mouse move event? Do we know it gets filtered out in the window manager, or does it lead to double event handling? brecht: I guess this event is often redundant, and already handed through a mouse move event? Do we…
		nicholas_rishelAuthorUnsubmitted Done Inline Actions This would not generally be redundant because tablet events (Wintab and WinPointer iirc) are asynchronously ordered from mouse events. If we're receiving a button event while a tablet is present, either Wintab handling failed to steal the event from Windows event queue (common case) or the mouse event was not generated from the stylus (e.g. a tablet pad's express buttons). In general operators should be tolerant of spurious mouse events because 1. variable pressure without motion requires this and 2. Windows intentionally generates spurious mouse movements which are currently not filtered out. nicholas_rishel: This would not generally be redundant because tablet events (Wintab and WinPointer iirc) are…
		brechtUnsubmitted Not Done Inline Actions Ah, I missed that this code only runs for tablets. It seems reasonable then. I guess at worst on the WM side it will generate an extra inbetween mousemove event, which is not a problem. brecht: Ah, I missed that this code only runs for tablets. It seems reasonable then.

		LazyDodoUnsubmitted Not Done Inline Actions There's quite a few comparisons in the `[constant] [comparison] [variable]` form, while it is sometimes advocated as "the safe way, just in case you make a typo, and ignore all warnings the compiler emits about that" it also makes the code harder to read than necessary. I don't think we have any guidance in the code-style guide, given my personal preferences commonly being at odds with our code-style I'm going to defer the final decision here to @Brecht Van Lommel (brecht) Whatever way is chosen though, its application at this point is inconsistent `[constant] [comparison] [variable]` and `[variable] [comparison] [constant]` both appear in newly added code.
