[cairo] Resize image without using cairo_surface_set_device_scale

[Francesco Alfano]

In old cairo-1.8.8-3.1, under C in linux clone of RHEL 6.4, I need to 
implement a function that performs the same operations as

|void cairo_surface_set_device_scale (cairo_surface_t *surface, double 
x_scale, double y_scale); |

as this function is not available, how can I do ?
