progress component: binding order of "max" and "value" should not matter

[ducarroz]

when declaring a progress component in the serialization, you must bind the max property before you bind the value property.

The issue is that you cannot set a value property greater than the max property per design. Ideally the order of the binding declaration should not matter.

The following will failed show the proper progress value:

"progress": {
    "prototype": "matte/ui/progress.reel",
    "properties": {
        "element": {
            "#": "progress"
        },
        "max": 0,
        "value": 0
    },
    "bindings": {
        "value": {
            "<-": "@owner.value"
        },
        "max": {
            "<-": "@owner.max"
        }
    }
}
