Custom legend item tile size & legend item padding

For some of our chart designs, we want to have legend element tiles that were lines rather than boxes - i.e. legend element tiles that look like this:

Also we want to be able to control the amount of space in between each legend element for more fine-grained control over how it is displayed.

So I want to add custom config options for these:

legend: {
    // amount of padding to put between each legend element
    padding: 5,
    // define custom height and width for the legend item tile
    item: {
        tile: {
            width: 15,
            height: 2
        }
    }
}

The default values for width and height would be the current legend item size.

This useful configuration is not in the doc yet. That’s too bad! I just found it thanks to Google.

Item padding isn’t working when legend is ‘inset’:
