Change augmentation dot size

[liang seng]

Hi, my name is Seng and I am using Lilypond 2.18.2 on Windows 10.

I am using the Bravura font by adding the command:

\paper{ 

 #(define fonts

    (set-global-fonts

    #:music "profondo"

    #:brace "profondo"

    #:factor (/ staff-height pt 20) )) 

My questions is, is there a way to change the size of augmentation dots to make it bigger or smaller?

The Bravura font augmentation dots' sizes are about identical to the staccato dot.

Thank you.

Seng Liang.
