First, the text Hello World! is drawn to the surface. Then, I alter the

Hi Alex,
This is actually the correct behavior. You need to redraw the
background before writing the new text. The easiest way to do that is
with:
$app-draw_rect( undef, 0x00FF );
The undef there indicates that the entire surface should be used as
the rectangle. See draw_rect in
But the surface is not an SDLx::Surface ... maybe we should change that at
least on the text surface. I think that once you decide to rewrite on the
text surface it should do that.
How about we add $text-clear(); ?
