To start the animation in a cell, set the GtkCellRendererSpinner:active
property to true and increment the GtkCellRendererSpinner:pulse property
at regular intervals. The usual way to set the cell renderer properties
for each cell is to bind them to columns in your tree model using e.g.
gtk.tree_view_column.TreeViewColumn.addAttribute.
