Re: [pointerevents] Should pressure be set to 1 or .5 on devices that don't report it?

I've never maintained a popular drawing program, so I don't know what 
the typical relationship is between reported pressure and opacity; 
however, modulating line width with pressure is a near-ubiquitous 
pattern in tablet-based drawing apps.  In fact, the way you know if 
you're using an app that supports pressure is to press very lightly 
and see if the line width shrinks.

As far as Android and iOS, they are primarily touch-driven UIs, so 
they largely circumvent the problem of "What pressure should we map 
mouse events to?"  It would be interesting to try an app like 
[Paper]( on a force-touch iPhone and a 
legacy iPhone and compare line widths and perceived pressure.
