 Replying to [comment:1 ersts]:
 > It turns out this actually would have been a little easier as a plugin,
 but it should be core functionality. The issue at hand is that the layer
 itself does not know what is currently being display. draw() accepts a
 render context object which is used to determine what portion of the layer
 to display, but that object comes from the map canvas.

 What a handy addition to qgis!  I was thinking that it would be nice to
 have this functionality available using the legend right click menu.
