<div class="desc"><p>Paints every pixel of the framebuffer a single color, wiping whatever the previous frame drew. Call it first inside your <code>Render</code> handler so each frame starts from a known background instead of leftover pixels. The one argument is a color, which can be a named palette value such as <code>Color.MidnightBlue</code> or a raw hex literal like <code>0x0d1020</code>. After clearing, draw the scene on top and finish with <code>Screen.show()</code>.</p></div>
