it is not related with the inside padding, and yes it does try to follow the
css/ffmpeg vocabulary. 'boxborderw' refer to what css names: 'border-width',
but ffmpeg drawtext already has a 'borderw' option, that is actually 
used for what
css will call: font-weight. to be close to css, but not brake the 
already existing
naming convention for 'draxtext' I chose 'boxborderw'
I could have renamed the existing 'borderw' to a more close description 
but it would have been against policy#6 of ffmpeg '1.4 Development Policy'
i did test this option for single and multiline overlay text, and for 
cases were the
text offset is smaller then the border size
