[SDL] SDL Tablet Pressure

[Nicholas Retallack]

Hi SDL people.  Oh how I love SDL.

I had an ambitious idea for a competitive art game.  However, I
noticed SDL is yet to have any support for tablet pressure sensitivity
data.  Are there plans to add it to events (perhaps as a property of
"motion" and "button")?

GTK for linux and windows I believe already supports pressure
sensitivity.  But I'd really rather have all my favorite things in one
API than trying to mix them.  And it's open source, so why not.

I'm generally a busy guy, but if there's any way I could help with
this that would be cool.
