I disagree on this point.  It's true that the code in CairoOutputDev and
SplashOutputDev is similar in nature, since they implement the same
functionality for different backends.  Where SplashOutputDev calls
sPath->lineTo(x, y) CairoOutputDev calls cairo_line_to(cr, x,y) etc.
Maybe I'm missing something, in that case I encourage you to out
concrete examples of code that could be shared, or even better provide a
patch that consolidates this allegedly duplicated functionality.

cheers,
