NOTE: Move edges along normal fix. [optigon]
Add a hidden image construction

For images/textures that should not be seen in the outliner.
Wings standard magnet fix for preview dialogs
NOTE: Fixed View ClipPlane bug

Some calls have changed from list to tuple in the wx opengl code.
It was fixed three warnings present in the master branch:
1) wings_shape.erl:833: Warning: function button_menu_cmd/1 is unused (I realy defined it without be necessary)
2) wings_material.erl:229: Warning: variable 'Perm' is unused (Perm was "moved" to select_material/3 - I forgot to remove it in this header)
3) wings_wm_toplevel.erl:233: Warning: function ctrl_message/0 is unused (I forgot the line calling this function commented)
New dialog for Image Plane resource.
NOTE: It was improved the Image Plane resource by adding a dialog box for
enter options like: location, rotation around origin, lock it after
created and assign a transparent material for its back face (this make
possible to see trough the image plane in proxy mode). Thanks oort by the
idea and support as well to Ran13. [Micheus]
