Fix cast between incompatible function types warnings

warning: cast between incompatible function types from ‘cairo_status_t (*)(void *, const cairo_point_t *)’ {aka ‘enum _cairo_status (*)(void *, const struct _cairo_point *)’} to ‘cairo_status_t (*)(void *, const cairo_point_t *, const cairo_slope_t *)’ {aka ‘enum _cairo_status (*)(void *, const struct _cairo_point *, const struct _cairo_slope *)’} [-Wcast-function-type]
