Overview

Enhance the GETDYNAMICMAPOVERLAY HTTP API to allow the selection and overlay images to be rendered as separate images.

Motivation

Currently, MapGuide renders the selection and the overlay image as a single image. This requires all untiled layers to be redrawn whenever the selection is changed. This is an inefficient use of server-side rendering resources and it reduces multi-user performance for untiled maps.
