* Provide a proper implementation of
SpectrogramLayer::invalidatePixmapCaches(size_t, size_t) -- if the
region is only part of the cache's current valid area, crop the
valid area instead of resetting it completely. This makes a big
difference when first rendering a spectrogram that is zoomed out a
long way when the underlying calculation has not yet completed -- as
is a common case in Vect for example.
