Add support for wacom tablet pen pressure

[disjukr]

I think your tool is really great! It's feel like z-brush in the web!!
I applied tablet pen pressure to brush radius.
Sorry for my little english that I can't explain exactly about it..

Great, thanks !
I can't test it though... since I don't own wacom pen tablet.
By the way, on other sculpting software, the pressure act on brush radius or brush intensity ?
It wouldn't be difficult to actually put a button with a choice between radius/intensity but I don't know if it's relevant.

@stephomi Thank you for merging my PR! you very fast! :D
I'm not artist so I don't know about sculpting tool very well.. but probably pressure acts both on radius and intensity(sorry for I didn't apply pressure on intensity)

zbrush provide setting of tablet pressure like this. so it seems like acting on both of them.

On the other hand, photoshop(yes, it's not sculpting tool. but it providing pressure function) has simply provide the pressure option like this:

I think providing just two checkbox about radius and intensity is maybe enough to user..

such like:

pressure
radius: on / off
intensity: on / off

Thanks for the information's digging :)

I've just checked on sculptris, and it's once again an on/off button for the radius/intensity.
The two checkbox solution is fine.

Hmm, my Wacom Intuos GD 9x12 doesn't work, radius and intensity are always the same.
