This change allows users to choose which method to use when running the simplify geometries algorithm, with choices of the existing distance based (Douglas Peucker) algorithm, area based (Visvalingam) algorithm and snap-to-grid. Visvaligam in particular usually results in more cartographically pleasing simplification over the standard distance based methods.
