In GimpLineArt, use the "invalidate-preview" signal of the input
viewable, instead of its "painted" or "rendered" signals, for
asynchronously computing the line art. Subsequently, remove the
aforementioned signals from GimpDrawable and GimpProjection,
respectively. This simplifies the code, and reduces the number of
signals.
