+<h4 class="subsection">2.4.5 Fonts</h4>
+
+<p>Unlike the traditional TrueType font format that many are accustomed
+to, Chickadee loads and renders bitmap fonts in the
+<a href="http://www.angelcode.com/products/bmfont/doc/file_format.html">Angel Code format</a>. But why use this seemingly obscure format? It&rsquo;s
+easy to find TTFs but not easy to find FNTs (the canonical file
+extension used for Angel Code fonts) and bitmap fonts don&rsquo;t scale
+well. The reason is efficiency.
+</p>
+<p>If all of the glyphs of a font are pre-rendered and packed into an
+image file then it becomes possible to use a texture atlas
+(see <a href="Textures.html#Textures">Textures</a>) and a sprite batch (see <a href="Sprites.html#Sprites">Sprites</a>) when
+rendering, which is a more efficient way to render fonts than using,
+say, <a href="https://www.libsdl.org/projects/SDL_ttf/">SDL_ttf</a> or other
+solutions that involve using the FreeType library directly.
+</p>
+<p>Now what about scaling? In libraries that use TTF fonts, one must
+choose the size that the glyphs will be rasterized at up front. To
+use <code>n</code> sizes of the same font, one must load <code>n</code> variants
+of that font. If the size of the text is dynamic, some kind of
+texture scaling algorithm must be used and the text will inevitably
+look blurry. At first glance, using bitmap fonts seem to have an even
+worse issue. Instead of just loading the same font <code>n</code> times at
+different sizes, one would need to generate <code>n</code> image files for
+each font size needed. This is where the &ldquo;signed distance field&rdquo;
+rendering technique comes in. Introduced by
+<a href="http://www.valvesoftware.com/.../2007/SIGGRAPH2007_AlphaTestedMagnification.pdf">Valve</a> in 2007, signed distance field fonts can be efficiently stored
+in a bitmap and be rendered at arbitrary scale factors with good
+results. Chickadee can render both traditional bitmap fonts and
+signed distance field fonts. <em>Signed distance field font
+rendering is not yet available, so be patient.</em>
+</p>
+<p>While Chickadee does not yet offer a tool for converting TTF fonts
+into FNT fonts, tools such as
+<a href="https://github.com/libgdx/libgdx/wiki/Hiero">Hiero</a> may be used
+in the meantime.

-<h4 class="subsection">2.4.2 Sprites</h4>
+<h4 class="subsection">2.4.3 Sprites</h4>
+
+<p>For those who are new to this game, a sprite is a 2D rectangular
+bitmap that is rendered to the screen. For 2D games, sprites are the
+most essential graphical abstraction. They are used for drawing maps,
+players, NPCs, items, particles, text, etc. In Chickadee, bitmaps are
+stored in textures (see <a href="Textures.html#Textures">Textures</a>) and can be used to draw sprites
+via the <code>draw-sprite</code> procedure.
+</p>
+<dl>
+<dt><a name="index-draw_002dsprite"></a>Scheme Procedure: <strong>draw-sprite</strong> <em><var>texture</var> <var>region</var> [#:scale] [#:rotation] [#:blend-mode alpha] [#:texture-region] [#:shader]</em></dt>
+</dl>
+
+<p>It&rsquo;s not uncommon to need to draw hundreds or thousands of sprites
+each frame. However, GPUs (graphics processing units) are tricky
+beasts that prefer to be sent few, large chunks of data to render
+rather than many, small chunks. Using <code>draw-sprite</code> on its own
+will involve at least one GPU call <em>per sprite</em>, which will
+quickly lead to poor performance. To deal with this, a technique
+known as &ldquo;sprite batching&rdquo; can be used. Instead of drawing each
+sprite immediately, the sprite batch will build up a large of buffer
+of sprites to draw and defer rendering until the last possible moment.
+Batching isn&rsquo;t a panacea, though. Batching only works if the sprites
+being drawn share as much in common as possible. Every time you draw
+a sprite with a different texture or blend mode, the batch will be
+sent off to the GPU. Therefore, batching is most useful if you
+minimize such changes. A good strategy for reducing texture changes
+is to stuff many bitmaps into a single image file and create a
+&ldquo;texture atlas&rdquo; (see <a href="Textures.html#Textures">Textures</a>) to access the sub-images within.
+</p>
+<p>Taking advantage of sprite batching in Chickadee is easy, just wrap
+the code that is calling <code>draw-sprite</code> a lot in the
+<code>with-batched-sprites</code> form.
+</p>
+<dl>
+<dt><a name="index-with_002dbatched_002dsprites"></a>Scheme Syntax: <strong>with-batched-sprites</strong> <em><var>body</var> &hellip;</em></dt>
+<dd><p>Use batched rendering for all <code>draw-sprite</code> calls within
+<var>body</var>.
+</p></dd></dl>
+
+<p>With a basic sprite abstraction in place, it&rsquo;s possible to build other
+abstractions on top of it. One such example is the &ldquo;nine patch&rdquo;. A
+nine patch is a sprite that can be rendered at various sizes without
+becoming distorted. This is achieved by diving up the sprite into
+nine regions:
+</p>
+<ul>
+<li> the center, which can be scaled horizontally and vertically
+</li><li> the four corners, which can never be scaled
+</li><li> the left and right sides, which can be scaled vertically
+</li><li> the top and bottom sides, which can be scaled horizontally
+</li></ul>
+<p>The one caveat is that the bitmap regions must be designed in such a
+way so that they are not distorted when stretched along the affected
+axes. For example, that means that the top and bottom sides could
+have varying colored pixels vertically, but not horizontally.
+</p>
+<p>The most common application of this technique is for graphical user
+interface widgets like buttons and dialog boxes. By using a nine
+patch, they can be rendered at any size without unappealing scaling
+artifacts.
+</p>
