Gideros Repeating and Clipping Background

Unknown

I want to have a background with a repeating x-axis, that can be moved horizontally. What I have so far:

local background = Texture.new("parallax01.png", true, {wrap = Texture.REPEAT})

local shape = Shape.new()
shape:setFillStyle(Shape.TEXTURE, background)
shape:beginPath(Shape.NON_ZERO)

shape:moveTo(0,100)
shape:lineTo(0,application:getDeviceWidth())

shape:lineTo(application:getDeviceHeight(),application:getDeviceWidth())
shape:lineTo(application:getDeviceHeight(),100)

Can I somehow move the background image without changing the shape position? I am a total Gideros noob and I could not find anything useful. Thanks.

Then press 'Start', look at the sea in the map.

(it moves vert and horiz using a sin/cos wave)
