Using a vector to represent a list of painting commands results in many reallocations, especially on pages with a lot of content. This change addresses it by introducing a SegmentedVector, which allows fast appending by representing a list as a sequence of fixed-size vectors. Currently, this new data structure supports only the operations used in RecordingPainter, which are appending and iterating.
