This function transforms layout's informations into a position matrix useful for
`ADEgS`

and for `lattice`

graphics.

`mat` |
a matrix indicating the location of figures to display (each value must be 0 or a positive integer) or a two-length vector indicating the number of rows and columns in the corresponding layout. |

`widths` |
a vector of relative values for the columns' widths on the device. Their sum must be equal to the number of columns. |

`heights` |
a vector of relative values for the rows' heights on the device. Their sum must be equal to the number of rows. |

`ng` |
a value for the number of positions needed (i.e. the number of graphics to plot) |

`square` |
a logical indicating if the graphics is an isometric plot |

A four-columns matrix indicating the coordinates (in normalized parent coordinates `npc`

)
of the top-right and bottom-left hand corners of each displayed figure on the device.

This function is strongly inspired by the `layout`

function in `graphics`

package.
