Adding point, line, polygon, text, and raster symbolizer constructors. This paves the way for rendering multiple symbolizers per rule. The SLD parser now successfully round-trips documents with multiple symbolizers and multiple FeatureTypeStyle elements (through the symbolizer zIndex property). The Style2 (yes, ack) constructor is used to represent a collection of rules with multiple symbolizers. Style2 objects are currently only used by the SLD parser if the multipleSymbolizer property is set to true. Future enhancements to the renderers can be made to account for multiple symbolizers. r=ahocevar (closes #2760).
