Adding members not specified by GeoJSON

[Conradaek]

I would like to suggest that a nice feature would be possibility do add any members to the GeoJSON object. I mean objects that are not specified in GeoJSON standard.

E.g. I am working now on a project, where PHP script will be outputting GeoJSON data. The data will be loaded via AJAX to a JavaScript and then load a Google Map based on the data.

I want to pass via GeoJSON some settings to set up a map e.g. an initial zoom value.

So let's say I have a GeoJSON FeatureColletion object. The collection is made of 1 feature (Point). I am specifying an initial zoom value as 2-nd member. I want my GeoJSON look this:

{
    "type":"FeatureCollection",
    "zoom": 12,
    "bbox":[
        19.967651,
        53.537043,
        19.967651,
        53.537043
    ],
    "features":[
        {
            "type":"Feature",
            "geometry":{
                "type":"Point",
                "coordinates":[
                    19.967651,
                    53.537043
                ]
            },
            "properties": null
        }
    ]
}

As I understand the specification of GeoJSON standard, it is allowed to add such members.

What do you think about it? I mean, what do you think about extending your lib so that you can add other members (not specified in a GeoJSON spec).

This is planned, likely in a 1.1 release. I recall seeing this in the spec, but it was after I had already released 1.0 -- and I never got around to creating a TODO ticket for it.
