<div class="desc"><p>Draws a string using Ludic's built-in bitmap font, starting at the top-left pixel <code>(x, y)</code>. The <code>scale</code> is an integer multiplier: <code>1</code> is the native font size, <code>2</code> is double-height and double-width, and so on — there are no fractional sizes. Use it for labels, menus, and messages such as titles or "GAME OVER"; for numbers that change every frame prefer <code>Screen.draw_number</code>, which needs no string conversion. The text is drawn in the given color over whatever is already on screen.</p></div>
