Adds a line to the current patch from the current point to position
(x, y) in pattern-space coordinates.
If there is no current point before the call to
cairo_mesh_pattern_line_to() this function will behave as
cairo_mesh_pattern_move_to(pattern, x, y).
After this call the current point will be (x, y).
Note: If pattern is not a mesh pattern then pattern will be put
into an error status with a status of
CAIRO_STATUS_PATTERN_TYPE_MISMATCH. If pattern has no current
patch or the current patch already has 4 sides, pattern will be
put into an error status with a status of
CAIRO_STATUS_INVALID_MESH_CONSTRUCTION.
