Create a Layer class to access the ArcGIS 9.3 Map Export service. Patch by
Jeff Adams, from Avencia. r=me. Tested with the default service, and several other example map services from ESRI (like http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/export). Note that I don't believe this takes advantage of map caches; if we create a seperate layer for that, we should probably create a Layer.ArcGIS. namespace. (Closes #1749) git-svn-id: http://svn.openlayers.org/trunk/openlayers@8917 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
