Re: [pointerevents] pointerup pressure should always be 0

aside aside: Sorry - I don't quite know the protocol here. Hopefully I
 got it right now?

Some users have a soft touch and some have a heavy touch. To 
accomodate this the hardware needs to be able to handle a heavy touch 
(you can make it softer in software, but you can't make it heavier if 
you don't have the range to sense it). A control panel is provided to 
make the touch lighter for those with a lighter touch. If you have a 
soft touch you should adjust it in the tablet control panel so that t 
is adjusted everywhere (even including how hard to press to register a

Using 0.5 results in a mismatch between Pointer Evenets and all other 
applications/situations. Desktop apps will use 100% as will 
non-Pointer Event web apps. Only Pointer Event web apps. will be 
limited to 50%

Instead of pressure modulates width, lets take pressure modulates 
opacity as an example. A mouse will draw 100% dark line. A pressure 
stylus will draw a 0% to 100% dark line. But a non-pressure stylus 
will only ever draw 50% dark line? How do I draw a dark line with a 
non-pressure stylus? It's not like I can set the app. to draw lines at
 200% darkness to compensate.

As an engineer, when I see 0.00 to 1.00 I tend to think in percentages
 from none to full. If the resolution is lower I simply scale the 
values. With two bits of resolution I'd do 0%, 33%, 66% and 100%. If 
I'm going to drop the resolution to a single bit, I tend to think none
 and full, not none and half, so I would do 0% and 100% not 0% and 
50%. But maybe that's just me.
