#3264: the canvas renderer may mess up when rendering external graphics

 Priority:  major            |   Milestone:  2.11 Release
Component:  Renderer.Canvas  |     Version:  2.10

-----------------------------+----------------------------------------------
 The Canvas {{{drawImage}}} function to draw external graphics is called
 asynchronously when the Image is loaded. This causes problem when, for
 example, the map is moved or features are destroyed, between
 {{{drawExternalGraphic}}} and {{{canvas.drawImage}}}.

 There already is a TODO comment about this in the {{{onLoad}}} inner
 function of {{{drawExternalGraphic}}}, but the comment does address the
 case where a {{{destroyFeatures}}} occurs between before {{{drawImage}}}
 is called.

 Working on that now...
