Bug ID: 423273
Summary: Gradient Map Filter uses uncached colorAt()

Callgrind map
the gradient map uses KoStopGradient::colorAt() without any caching which is
extremely slow because that retrieves a colorspace all the time. Using the
CachedGradient from the gradient painter doesn't seem easy or obvious.
