Overview

Correct rendering of road networks requires ordering. Major roads should be rendered over the top of minor roads.

Motivation

Currently MapGuide Studio exposes the ability to order individual styles within a layer,
however, the server doesn't support ordered rendering. The only work around currently
is to break road networks into separate layers.

Proposed Solution

Add support to the rendering engine to render layer styles in ordered passes.

This should only require changes to the rendering engine, there would be no
xml schema schema changes required

Implications

None.

Test Plan

None.
