#14288: Loading a custom layer that includes gfx fails under IE7/8

 If a custom layer file is created that includes dojox.gfx.canvas, and that
 layer file is loaded on a browser which doesn't properly support the
 canvas element, then the following code will cause the layer file
 evaluation to stop and an Error is raised:
 {{{
 #!js
 if(typeof dojo.doc.createElement("canvas").getContext("2d").fillText !=
 "function"){
     canvas.Text.extend({
         getTextWidth: function(){
             return 0;
         },
         _renderShape: function(){}
     });
 }
 }}}
 Specifically, IE browsers break on the call to getContext.  This is
 problematic primarily because this code will run regardless of whether the
 browser supports canvas or not
