+/**
+ * <p>This class can be used to load {@link android.widget.Adapter adapters} defined in
+ * XML resources. XML-defined adapters can be used to easily create adapters in your
+ * own application or to pass adapters to other processes.</p>
+ * 
+ * <h2>Types of adapters</h2>
+ * <p>Adapters defined using XML resources can only be one of the following supported
+ * types. Arbitrary adapters are not supported to guarantee the safety of the loaded
+ * code when adapters are loaded across packages.</p>
+ * <ul>
+ *  <li><a href="#xml-cursor-adapter">Cursor adapter</a>: a cursor adapter can be used
+ *  to display the content of a cursor, most often coming from a content provider</li>
+ * </ul>
+ * <p>The complete XML format definition of each adapter type is available below.</p>
+ * 
+ * <a name="xml-cursor-adapter" />
+ * <h2>Cursor adapter</h2>
+ * <p>A cursor adapter XML definition starts with the
+ * <a href="#xml-cursor-adapter-tag"><code>&lt;cursor-adapter /&gt;</code></a>
+ * tag and may contain one or more instances of the following tags:</p>
+ * <ul>
+ *  <li><a href="#xml-cursor-adapter-select-tag"><code>&lt;select /&gt;</code></a></li>
+ *  <li><a href="#xml-cursor-adapter-bind-tag"><code>&lt;bind /&gt;</code></a></li>
+ * </ul>
+ * 
+ * <a name="xml-cursor-adapter-tag" />
+ * <h3>&lt;cursor-adapter /&gt;</h3>
+ * <p>The <code>&lt;cursor-adapter /&gt;</code> element defines the beginning of the
+ * document and supports the following attributes:</p>
+ * <ul>
+ *  <li><code>android:layout</code>: Reference to the XML layout to be inflated for
+ *  each item of the adapter. This attribute is mandatory.</li>
+ *  <li><code>android:selection</code>: Selection expression, used when the
+ *  <code>android:uri</code> attribute is defined or when the adapter is loaded with
+ *  {@link android.widget.Adapters#loadCursorAdapter(android.content.Context, int, String, Object[])}.
+ *  This attribute is optional.</li>
+ *  <li><code>android:sortOrder</code>: Sort expression, used when the
+ *  <code>android:uri</code> attribute is defined or when the adapter is loaded with
+ *  {@link android.widget.Adapters#loadCursorAdapter(android.content.Context, int, String, Object[])}.
+ *  This attribute is optional.</li>
+ *  <li><code>android:uri</code>: URI of the content provider to query to retrieve a cursor.
+ *  Specifying this attribute is equivalent to calling {@link android.widget.Adapters#loadCursorAdapter(android.content.Context, int, String, Object[])}.
+ *  If you call this method, the value of the XML attribute is ignored. This attribute is
+ *  optional.</li>
+ * </ul>
+ * <p>In addition, you can specify one or more instances of
+ * <a href="#xml-cursor-adapter-select-tag"><code>&lt;select /&gt;</code></a> and
+ * <a href="#xml-cursor-adapter-bind-tag"><code>&lt;bind /&gt;</code></a> tags as children
+ * of <code>&lt;cursor-adapter /&gt;</code>.</p>
+ * 
+ * <a name="xml-cursor-adapter-select-tag" />
+ * <h3>&lt;select /&gt;</h3>
+ * <p>The <code>&lt;select /&gt;</code> tag is used to select columns from the cursor
+ * when doing the query. This can be very useful when using transformations in the
+ * <code>&lt;bind /&gt;</code> elements. It can also be very useful if you are providing
+ * your own <a href="#xml-cursor-adapter-bind-data-types">binder</a> or
+ * <a href="#xml-cursor-adapter-bind-data-types">transformation</a> classes.
+ * <code>&lt;select /&gt;</code> elements are ignored if you supply the cursor yourself.</p>
+ * <p>The <code>&lt;select /&gt;</code> supports the following attributes:</p>
+ * <ul>
+ *  <li><code>android:column</code>: Name of the column to select in the cursor during the
+ *  query operation</li>
+ * </ul>
+ * <p><strong>Note:</strong> The column named <code>_id</code> is always implicitely
+ * selected.</p>
+ * 
+ * <a name="xml-cursor-adapter-bind-tag" />
+ * <h3>&lt;bind /&gt;</h3>
+ * <p>The <code>&lt;bind /&gt;</code> tag is used to bind a column from the cursor to
+ * a {@link android.view.View}. A column bound using this tag is automatically selected
+ * during the query and a matching
+ * <a href="#xml-cursor-adapter-select-tag"><code>&lt;select /&gt;</code> tag is therefore
+ * not required.</p>
+ * 
+ * <p>Each binding is declared as a one to one matching but
+ * custom binder classes or special
+ * <a href="#xml-cursor-adapter-bind-data-transformation">data transformations</a> can
+ * allow you to bind several columns to a single view. In this case you must use the
+ * <a href="#xml-cursor-adapter-select-tag"><code>&lt;select /&gt;</code> tag to make
+ * sure any required column is part of the query.</p>
+ * 
+ * <p>The <code>&lt;bind /&gt;</code> tag supports the following attributes:</p>
+ * <ul>
+ *  <li><code>android:from</code>: The name of the column to bind from.
+ *  This attribute is mandatory.</li>
+ *  <li><code>android:to</code>: The id of the view to bind to. This attribute is mandatory.</li>
+ *  <li><code>android:as</code>: The <a href="#xml-cursor-adapter-bind-data-types">data type</a>
+ *  of the binding. This attribute is mandatory.</li>
+ * </ul>
+ * 
+ * <p>In addition, a <code>&lt;bind /&gt;</code> can contain zero or more instances of
+ * <a href="#xml-cursor-adapter-bind-data-transformation">data transformations</a> chilren
+ * tags.</p>
+ *
+ * <a name="xml-cursor-adapter-bind-data-types" />
+ * <h4>Binding data types</h4>
+ * <p>For a binding to occur the data type of the bound column/view pair must be specified.
+ * The following data types are currently supported:</p>
+ * <ul>
+ *  <li><code>string</code>: The content of the column is interpreted as a string and must be
+ *  bound to a {@link android.widget.TextView}</li>
+ *  <li><code>image</code>: The content of the column is interpreted as a blob describing an
+ *  image and must be bound to an {@link android.widget.ImageView}</li>
+ *  <li><code>image-uri</code>: The content of the column is interpreted as a URI to an image
+ *  and must be bound to an {@link android.widget.ImageView}</li>
+ *  <li><code>drawable</code>: The content of the column is interpreted as a resource id to a
+ *  drawable and must be bound to an {@link android.widget.ImageView}</li>
+ *  <li>A fully qualified class name: The name of a class corresponding to an implementation of
+ *  {@link android.widget.Adapters.CursorBinder}. Cursor binders can be used to provide
+ *  bindings not supported by default. Custom binders cannot be used with
+ *  {@link android.content.Context#isRestricted() restricted contexts}, for instance in an
+ *  app widget</li>
+ * </ul>
+ * 
+ * <a name="xml-cursor-adapter-bind-transformation" />
+ * <h4>Binding transformations</h4>
+ * <p>When defining a data binding you can specify an optional transformation by using one
+ * of the following tags as a child of a <code>&lt;bind /&gt;</code> elements:</p>
+ * <ul>
+ *  <li><code>&lt;map /&gt;</code>: Maps a constant string to a string or a resource. Use
+ *  one instance of this tag per value you want to map</li>
+ *  <li><code>&lt;transform /&gt;</code>: Transforms a column's value using an expression
+ *  or an instance of {@link android.widget.Adapters.CursorTransformation}</li>
+ * </ul>
+ * <p>While several <code>&lt;map /&gt;</code> tags can be used at the same time, you cannot
+ * mix <code>&lt;map /&gt;</code> and <code>&lt;transform /&gt;</code> tags. If several
+ * <code>&lt;transform /&gt;</code> tags are specified, only the last one is retained.</p>
+ * 
+ * <a name="xml-cursor-adapter-bind-transformation-map" />
+ * <p><strong>&lt;map /&gt;</strong></p>
+ * <p>A map element simply specifies a value to match from and a value to match to. When
+ * a column's value equals the value to match from, it is replaced with the value to match
+ * to. The following attributes are supported:</p>
+ * <ul>
+ *  <li><code>android:fromValue</code>: The value to match from. This attribute is mandatory</li>
+ *  <li><code>android:toValue</code>: The value to match to. This value can be either a string
+ *  or a resource identifier. This value is interpreted as a resource identifier when the
+ *  data binding is of type <code>drawable</code>. This attribute is mandatory</li>
+ * </ul>
+ * 
+ * <a name="xml-cursor-adapter-bind-transformation-transform" />
+ * <p><strong>&lt;transform /&gt;</strong></p>
+ * <p>A simple transform that occurs either by calling a specified class or by performing
+ * simple text substitution. The following attributes are supported:</p>
+ * <ul>
+ *  <li><code>android:withExpression</code>: The transformation expression. The expression is
+ *  a string containing column names surrounded with curly braces { and }. During the
+ *  transformation each column name is replaced by its value. All columns must have been
+ *  selected in the query. An example of expression is <code>"First name: {first_name},

+ * A resource that manages a number of alternate Drawables, and which actually draws the one which
+ * size matches the most closely the drawing bounds. Providing several pre-scaled version of the
+ * drawable helps minimizing the aliasing artifacts that can be introduced by the scaling.
+ *
+ * <p>
+ * Use {@link #addDrawable(Drawable)} to define the different Drawables that will represent the
+ * mipmap levels of this MipmapDrawable. The mipmap Drawable that will actually be used when this
+ * MipmapDrawable is drawn is the one which has the smallest intrinsic height greater or equal than
+ * the bounds' height. This selection ensures that the best available mipmap level is scaled down to
+ * draw this MipmapDrawable.
+ * </p>
+ *
+ * If the bounds' height is larger than the largest mipmap, the largest mipmap will be scaled up.
+ * Note that Drawables without intrinsic height (i.e. with a negative value, such as Color) will
+ * only be used if no other mipmap Drawable are provided. The Drawables' intrinsic heights should
+ * not be changed after the Drawable has been added to this MipmapDrawable.
+ *
+ * <p>
+ * The different mipmaps' parameters (opacity, padding, color filter, gravity...) should typically
+ * be similar to ensure a continuous visual appearance when the MipmapDrawable is scaled. The aspect
+ * ratio of the different mipmaps should especially be equal.
+ * </p>
+ *
+ * A typical example use of a MipmapDrawable would be for an image which is intended to be scaled at
+ * various sizes, and for which one wants to provide pre-scaled versions to precisely control its
+ * appearance.
+ *
+ * <p>
+ * The intrinsic size of a MipmapDrawable are inferred from those of the largest mipmap (in terms of
+ * {@link Drawable#getIntrinsicHeight()}). On the opposite, its minimum
+ * size is defined by the smallest provided mipmap.
+ * </p>
+
+ * It can be defined in an XML file with the <code>&lt;mipmap></code> element.
+ * Each mipmap Drawable is defined in a nested <code>&lt;item></code>. For example:
+ * <pre>
+ * &lt;mipmap xmlns:android="http://schemas.android.com/apk/res/android">
+ *  &lt;item android:drawable="@drawable/my_image_8" />
+ *  &lt;item android:drawable="@drawable/my_image_32" />
+ *  &lt;item android:drawable="@drawable/my_image_128" />
+ * &lt;/mipmap>
+ *</pre>
+ * <p>
+ * With this XML saved into the res/drawable/ folder of the project, it can be referenced as
+ * the drawable for an {@link android.widget.ImageView}. Assuming that the heights of the provided
+ * drawables are respectively 8, 32 and 128 pixels, the first one will be scaled down when the
+ * bounds' height is lower or equal than 8 pixels. The second drawable will then be used up to a
+ * height of 32 pixels and the largest drawable will be used for greater heights.

+/**
+ * Shape Arabic text on a character basis.
+ *
+ * <p>ArabicShaping performs basic operations for "shaping" Arabic text. It is most
+ * useful for use with legacy data formats and legacy display technology
+ * (simple terminals). All operations are performed on Unicode characters.</p>
+ *
+ * <p>Text-based shaping means that some character code points in the text are
+ * replaced by others depending on the context. It transforms one kind of text
+ * into another. In comparison, modern displays for Arabic text select
+ * appropriate, context-dependent font glyphs for each text element, which means
+ * that they transform text into a glyph vector.</p>
+ *
+ * <p>Text transformations are necessary when modern display technology is not
+ * available or when text needs to be transformed to or from legacy formats that
+ * use "shaped" characters. Since the Arabic script is cursive, connecting
+ * adjacent letters to each other, computers select images for each letter based
+ * on the surrounding letters. This usually results in four images per Arabic
+ * letter: initial, middle, final, and isolated forms. In Unicode, on the other
+ * hand, letters are normally stored abstract, and a display system is expected
+ * to select the necessary glyphs. (This makes searching and other text
+ * processing easier because the same letter has only one code.) It is possible
+ * to mimic this with text transformations because there are characters in
+ * Unicode that are rendered as letters with a specific shape
+ * (or cursive connectivity). They were included for interoperability with
+ * legacy systems and codepages, and for unsophisticated display systems.</p>
+ *
+ * <p>A second kind of text transformations is supported for Arabic digits:
+ * For compatibility with legacy codepages that only include European digits,
+ * it is possible to replace one set of digits by another, changing the
+ * character code points. These operations can be performed for either
+ * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic
+ * digits (U+06f0...U+06f9).</p>
+ *
+ * <p>Some replacements may result in more or fewer characters (code points).
+ * By default, this means that the destination buffer may receive text with a
+ * length different from the source length. Some legacy systems rely on the
+ * length of the text to be constant. They expect extra spaces to be added
+ * or consumed either next to the affected character or at the end of the
+ * text.</p>

+Repro steps:
+
+build, install and run the attached test program TestViewport.apk
+
+Run on Sapphire with Froyo.
+
+The program clears the screen to blue, then draws a full screen white quad that
+is alligned to the screen.
+(Therefore the whole screen should appear to be white.)
+
+
+Note that screen is all white.
+
+Rotate screen 90 degrees.
+
+Expected: screen is still all white.
+
+Actual: screen is blue with offset white rectangle.
+
+This bug only happens on Sapphire, it works correctly on Passion.
+
+What happens:
+
+I think the bug is that the gl.glViewport() call in onSurfaceChanged() is
+being ignored by the OpenGL driver.
+
+NOTE: If a gl.glViewport call is added at the beginning of the onDrawFrame()
+call (which means it is called before every draw), the program runs correctly.
