There was an ability to repeat the image in 2.49 that seems to not be available in 2.73.
In Blender 2.49, in the View Menu, View Properties > Repeat Image filled the image editor window with a 2D array of the image. I found this very useful, but have not found a way to do it in Blender 2.73. I checked User Preferences to see if the capability existed although not through a menu. I did not find it.
Is there a way to do this that I missed, or could there be an add-on that includes this feature?
