pattern -- a cairo-pattern-t instance

x0 -- a double float x coordinate of the first point
y0 -- a double float y coordinate of the first point
y0 -- a double float x coordinate of the second point
y1 -- a double float y coordinate of the second point
status -- :success, or :pattern-type-mismatch if pattern is not a linear gradient pattern
