TextureMapToSphere reverses textures

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

I have a user that wants to map the world to a sphere. ParaView 3.6.2, XP, local server.

Sources/ SuperQuadric. Theta resolution == 128. Phi Resolution = 128.
Turn off Toroidal.
Apply.
On the Display tab, Apply Texture.
Use the world map, found at http://www.oera.net/How2/PlanetTexs/EarthMap_2500x1250.jpg. [^] (Enter this on the Display tab)
Notice that the earth looks good.
Filters/ Alphabetical/ TextureMapToSphere.
On the Display tab, Apply Texture.
Notice that the earth looks reversed.

We are speculating this is because the original developer of this filter wanted to be able to wrap the texture on a sphere, and that the user then moved the eye INSIDE of the sphere - thus making the sphere the 3d window background. Thus, please make a user selectable option allowing the user to reverse the texture if desired.
