LibGfx: Fix classic theme frame transparency check

Browse source 
We shouldn't use the title stripe or title shadow colors to determine
whether the frame itself is going to have alpha channels or not. This
caused e.g. the classic theme's window frame to be rendered as
transparency just because the stripe color had an alpha channel of 0.
