`CellView.Size()` clips all models to a maximum of 2x2 cells

[chrBrd]

According to the comments in this function it's supposed to return a minimum 2x2 square:

// Size returns the content size, based on the model.
func (a *CellView) Size() (int, int) {
	// We always return a minimum of two rows, and two columns.
	w, h := a.model.GetBounds()
	// Clip to a 2x2 minimum square; we can scroll within that.
	if w > 2 {
		w = 2
	}
	if h > 2 {
		h = 2
	}
	return w, h
}

However the comparison operators are incorrect, so it's actually returning a maximum 2x2 square
