+
+<p>A 9-patch is a method of rendering a texture so that it can be
+stretched to cover an area of any size without becoming distorted.
+This is achieved by dividing up the sprite into nine regions:
+</p>
+<ul>
+<li> the center, which can be stretched or tiled horizontally and vertically
+</li><li> the four corners, which are never stretched or tiled
+</li><li> the left and right sides, which can be stretched or tiled vertically
+</li><li> the top and bottom sides, which can be stretched or tiled horizontally
+</li></ul>
+
+<p>The most common application of this technique is for graphical user
+interface widgets like buttons and dialog boxes which are often
+dynamically resizable.  By using a 9-patch, they can be rendered at
+any size without scaling artifacts.
+</p>

 <p>Much like the vector API, the matrix API is commonly used in
 performance critical code paths.  In order to reduce the amount of
 garbage generated and improve matrix multiplication performance, there
 are many procedures that perform in-place modifications of matrix
 objects.

-<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 dividing 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.
