Feature Request: shadow / white glow for text in titlebar

[kneckergit]

When using this incredible theme (kudos) to recreate the Aero style of Windows 7, or just using transparency in general in titlebars, the font becomes unreadable. If the text has a dark color, it becomes unreadable on dark wallpapers and vice versa with bright colors. The solution for this problem was circumvented by Redmond in Windows 7, with a bright or dark glow behind the text on titlebars - which looked smart and elegant by the way. So, is there any chance of having (coloured) shadows on text in titlebars?
Thank you for this brilliant theme!
