As we talked about over IRC, since Cairo doesn't support saving separate stroke
and fill colors on the context, it obviously doesn't have a "draw" fast path.

Cairo GraphicsContext code needs to move to this model anyway:

someFillMethod()
{
// grab the current fill color off of the GraphicContextState
// set it as the "cairo source"
// do the actual fill
}

instead of how CG works, which is to just pipe the "set fill color" calls
straight down into the CoreGraphics context.

Also, because Cairo doesn't have a built-in fast-path for "draw", Cairo (and
any other graphics library which doesn't support simultaneous fill + stroke)
can just write:

GraphicsContext::drawPath()
{
    fillPath();
    strokePath();
}
