private void CreateTags(TextBuffer buffer)
{
// Create a bunch of tags. Note that it's also possible to
// create tags with gtk_text_tag_new() then add them to the
// tag table for the buffer, gtk_text_buffer_create_tag() is
// just a convenience function. Also note that you don't have
// to give tags a name; pass NULL for the name to create an
// anonymous tag.
//
// In any real app, another useful optimization would be to create
// a GtkTextTagTable in advance, and reuse the same tag table for
// all the buffers with the same tag set, instead of creating
// new copies of the same tags for every buffer.
//
// Tags are assigned default priorities in order of addition to the
// tag table. That is, tags created later that affect the same text
// property affected by an earlier tag will override the earlier
// tag. You can modify tag priorities with
// gtk_text_tag_set_priority().
