Feature request: It should be possible to fill the background of an SVG icon with the Vector Flood Fill Tool

[Peter Panino]

Regarding this problem: 

After loading an SVG icon, it should be possible to fill the transparent background of the loaded SVG icon with the Vector Flood Fill Tool. This would save a lot of time: Instead of cumbersomely creating a background shape, you can fill the transparent background of the SVG icon with a convenient single click.

In other words, clicking with the Vector Flood Fill Tool on an empty transparent area should create a background rectangle with the current color filling out the whole document area.
