Update from @OnlyInAmerica from OpenSpritz-Android
The pivot indicator length can set from the FontMetrics.bottom - more info can be found here http://evendanan.net/2011/12/Font-Metrics-in-Java-OR-How-the-hell-Should-I-Position-This-Font/

While the top and bottom padding can be determined by multiply the pivot indicator length by 2 which should make the indicator line never overlapping the pivot letter

The attributes padding, paddingTop, and paddingBottom will be additional padding for the calculated padding in the above statement.
Remove old circle padding
reset the padding if the font size gets changed
remove unused local variable
Add seek bar to change text size
Change to version 0.2.0
