Evas masking: Skip GL fast path if image has fill options

If the image is not "filled", then we can't assume its image
source geometry is the same as its texture geometry.

Note: Implementing a fast path for non-filled images would
      require a hell of a lot more work (need to cut the render
      into a lot more triangles) for little real-life use.
