no drag for ColorWheel in Android mode

[mulholland77]

Hi,

I develop an App with your great library on Android.
Click and Drag doesn't work for the ColorWheel controller in Android Mode.

I can only use click point in this mode so it's not very intuitive.

I haven't drag issue with sliders or other color selector, like ControlP5 Color picker in Android.
No drag issue to with the colorWheel controller in desktop mode.

Is there a simple way to solve that?

Test with ControlP5 ColorWheel exemple
Processing 3.0 in Android mode
OS 10.10.4 with java build 1.8.0_73-b02 (last update)

Android 5.1.1

Best regards
