simplify code

[horriblename]

Correct me if I'm wrong but the following code does the same as ui.screen.Clear() right?

func (ui *ui) draw(nav *nav) {
	st := tcell.StyleDefault

	wtot, htot := ui.screen.Size()
	for i := 0; i < wtot; i++ {
		for j := 0; j < htot; j++ {
			ui.screen.SetContent(i, j, ' ', nil, st)
		}
	}

From the docs:

Clear erases the screen. The contents of any screen buffers will also be cleared. This has the logical effect of filling the screen with spaces, using the global default style.
