[visionegg] gaussian mask on image

I tried to put a gaussian mask (Mask2D) on a graphic image by TextureStimulus,
but an error occured, which said

        TypeError: draw_masked_quad() takes exactly 10 arguments (9 given)

So, I added a depth arugument ("8" or "32") to draw_masked_quad in Texture.py.
It seems that the error is avoided, but the image does not appear.

Does anyone know how to put a gaussian mask on an image texture ?
