Signed distance from points `p`

to boundary of rectangle to
allow easy definition of regions in `distmesh2d`

.

1 | ```
mesh.drectangle(p, x1 = -1/2, y1 = -1/2, x2 = 1/2, y2 = 1/2, ...)
``` |

`p` |
A matrix with 2 columns, each row representing a point in the plane. |

`x1` |
lower left corner of rectangle |

`y1` |
lower left corner of rectangle |

`x2` |
upper right corner of rectangle |

`y2` |
upper right corner of rectangle |

`...` |
additional arguments (not used) |

a vector of length `nrow(p)`

containing the signed distances
