Texture mapping works only when "MappingWidget" is on

Not sure this was discussed before. Texture scaling in the viewport doesn’t reflect changes for XYZ mapping parameters. It works correct only if the MappingWidget is on. It seems that texture scale reverts to default values and mapping type if widget is off.

Tested on i7-5930k and nvidia GTX 980 Ti in Rendered display mode.
