This renderer merges (or unions/dissolves) the line or polygon features from a layer prior to rendering them. It's useful for rendering a polygon layer with overlapping features as one single "coverage" feature, or a line layer consisting of many smaller component line features using a regularly spaced marker line or similar. Internally, this just moves the guts of the existing inverted polygons renderer to a new base class, as that renderer already had an option to merge features prior to rendering. Basically it just exposes a new renderer to users which is the inverted polygon renderer without the inversion step!
