Problem Description

For phetsims/qa#871. I can't confirm using showPointerAreas but my guess is the touch area for the flux meter isn't dilated. It sometimes took me a couple tries to grab it, so I recommend making it a little larger (mainly the height could be larger).

Steps to Reproduce

Open sim in English
Go to Layer Model screen
Show flux meter
Drag flux meter to a new position

Thanks for the suggestion @amanda-phet!

@jbphet can you vertically dilate the touch area on the flux meter probe? Something along the lines of what was done for the slider thumbs would work.

I've added some dilation in the Y direction on both the 1.1 and master branches. @arouinfar - Does this look good to you? You can try it out on master if you prefer.

Thanks @jbphet! I tested it out on my phone and the flux meter probe was easy to grab.

On the iPad, in rc.2 the flux meter probe was easy to grab on both the Photons and Layer Model screens.
