//The device offset adds to the device coordinates determined by the coordinate
//transform matrix when drawing to a surface.
//
//One use case for this method is to create a surface that redirects a portion
//of drawing offscreen invisble to users of the Cairo api.
//Setting a transform is insufficent as queries such as DeviceToUser expose
//this offset.
//
//Note that the offset affects drawing to the surface as well
//as using the surface in a source pattern.
//
//The x and y components are in the unit of the surface's underlying device.
