Add support for localized non-world WMTS services.
Applies to Map Suite Desktop, WPF Desktop, MVC, Web, Silverlight and Services Editions.
Currently the WmtsOverlay is limited to supporting world-covering WMTS/tiling services like Google and Bing, which display maps in the Spherical Mercator projection. This proposed improvement would enhance the WmtsOverlay and related classes to expose access to the necessary parameters (projection, extent, etc.) needed for using localized WMTS services.
