Why is buf global variable?

Hi Chris,

I saw this variable is only here used. Why is "buf" a global variable?

Thanks, Diego

I have a demofx javafx 11 version and I saw this and I do not know the reason.

I probably had an accessor method for it at one point but then removed it. Looks like it can be safely turned into a local.
