only pass a real paint to drawPicture if we need to

drawPicture(..., paint)

If paint is non-null, drawPicture will always draw the picture into a
temp layer. Thus we should not blindly pass in a "filtered" paint unless
it will actually draw differently (other than the layer itself).

Side-effect: drawing into a layer is also much slower, so a 2nd reason
to not blindly pass in a non-null paint.
