+/**
+ * {@usesMathJax}
+ *
+ * <p>A {@link ColorSpace} is used to identify a specific organization of colors.
+ * Each color space is characterized by a {@link Model color model} that defines
+ * how a color value is represented (for instance the {@link Model#RGB RGB} color
+ * model defines a color value as a triplet of numbers).</p>
+ *
+ * <p>Each component of a color must fall within a valid range, specific to each
+ * color space, defined by {@link #getMinValue(int)} and {@link #getMaxValue(int)}
+ * This range is commonly \([0..1]\). While it is recommended to use values in the
+ * valid range, a color space always clamps input and output values when performing
+ * operations such as converting to a different color space.</p>
+ *
+ * <h3>Using color spaces</h3>
+ *
+ * <p>This implementation provides a pre-defined set of common color spaces
+ * described in the {@link Named} enum. To obtain an instance of one of the
+ * pre-defined color spaces, simply invoke {@link #get(Named)}:</p>
+ *
+ * <pre class="prettyprint">
+ * ColorSpace sRgb = ColorSpace.get(ColorSpace.Named.SRGB);
+ * </pre>
+ *
+ * <p>The {@link #get(Named)} method always returns the same instance for a given
+ * name. Color spaces with an {@link Model#RGB RGB} color model can be safely
+ * cast to {@link Rgb}. Doing so gives you access to more APIs to query various
+ * properties of RGB color models: color gamut primaries, transfer functions,
+ * conversions to and from linear space, etc. Please refer to {@link Rgb} for
+ * more information.</p>
+ *
+ * <p>The documentation of {@link Named} provides a detailed description of the
+ * various characteristics of each available color space.</p>
+ *
+ * <h3>Color space conversions</h3>
+
+ * <p>To allow conversion between color spaces, this implementation uses the CIE
+ * XYZ profile connection space (PCS). Color values can be converted to and from
+ * this PCS using {@link #toXyz(float[])} and {@link #fromXyz(float[])}.</p>
+ *
+ * <p>For color space with a non-RGB color model, the white point of the PCS
+ * <em>must be</em> the CIE standard illuminant D50. RGB color spaces use their
+ * native white point (D65 for {@link Named#SRGB sRGB} for instance and must
+ * undergo {@link Adaptation chromatic adaptation} as necessary.</p>
+ *
+ * <p>Since the white point of the PCS is not defined for RGB color space, it is
+ * highly recommended to use the variants of the {@link #connect(ColorSpace, ColorSpace)}
+ * method to perform conversions between color spaces. A color space can be
+ * manually adapted to a specific white point using {@link #adapt(ColorSpace, float[])}.
+ * Please refer to the documentation of {@link Rgb RGB color spaces} for more
+ * information. Several common CIE standard illuminants are provided in this
+ * class as reference (see {@link #ILLUMINANT_D65} or {@link #ILLUMINANT_D50}
+ * for instance).</p>
+ *
+ * <p>Here is an example of how to convert from a color space to another:</p>
+ *
+ * <pre class="prettyprint">
+ * // Convert from DCI-P3 to Rec.2020
+ * ColorSpace.Connector connector = ColorSpace.connect(
+ *         ColorSpace.get(ColorSpace.Named.DCI_P3),
+ *         ColorSpace.get(ColorSpace.Named.BT2020));
+ *
+ * float[] bt2020 = connector.transform(p3r, p3g, p3b);
+ * </pre>
+ *
+ * <p>You can easily convert to {@link Named#SRGB sRGB} by omitting the second
+ * parameter:</p>
+ *
+ * <pre class="prettyprint">
+ * // Convert from DCI-P3 to sRGB
+ * ColorSpace.Connector connector = ColorSpace.connect(ColorSpace.get(ColorSpace.Named.DCI_P3));
+ *
+ * float[] sRGB = connector.transform(p3r, p3g, p3b);
+ * </pre>
+ *
+ * <p>Conversions also work between color spaces with different color models:</p>
+ *
+ * <pre class="prettyprint">
+ * // Convert from CIE L*a*b* (color model Lab) to Rec.709 (color model RGB)
+ * ColorSpace.Connector connector = ColorSpace.connect(
+ *         ColorSpace.get(ColorSpace.Named.CIE_LAB),
+ *         ColorSpace.get(ColorSpace.Named.BT709));
+ * </pre>
+ *
+ * <h3>Color spaces and multi-threading</h3>
+ *
+ * <p>Color spaces and other related classes ({@link Connector} for instance)
+ * are immutable and stateless. They can be safely used from multiple concurrent
+ * threads.</p>
+ *
+ * <p>Public static methods provided by this class, such as {@link #get(Named)}
+ * and {@link #connect(ColorSpace, ColorSpace)}, are also guaranteed to be
+ * thread-safe.</p>
+ *
+ * @see #get(Named)
+ * @see Named
+ * @see Model
+ * @see Connector
+ * @see Adaptation

+     * point of an RGB color space is defined in the CIE xyY color space. This
+     * color space separates the chromaticity of a color, the x and y components,

+     * are internally converted to xyY.</p>

+     * between linear tristimulus values and non-linear electronic signal value.</p>
+     * <p>The <em>opto-electronic transfer function</em> (OETF or OECF) encodes
+     * tristimulus values in a scene to a non-linear electronic signal value.
+     * An OETF is often expressed as a power function with an exponent between

+     * a non-linear electronic signal value to a tristimulus value at the display.
+     * An EOTF is often expressed as a power function with an exponent between
+     * 1.8 and 2.6.</p>
+     * <p>Transfer functions are used as a compression scheme. For instance,
+     * linear sRGB values would normally require 11 to 12 bits of precision to
+     * store all values that can be perceived by the human eye. When encoding
+     * sRGB values using the appropriate OETF (see {@link Named#SRGB sRGB} for
+     * an exact mathematical description of that OETF), the values can be
+     * compressed to only 8 bits precision.</p>
+     * <p>When manipulating RGB values, particularly sRGB values, it is safe
+     * to assume that these values have been encoded with the appropriate
+     * OETF (unless noted otherwise). Encoded values are often said to be in
+     * "gamma space". They are therefore defined in a non-linear space. This
+     * in turns means that any linear operation applied to these values is
+     * going to yield mathematically incorrect results (any linear interpolation
+     * such as gradient generation for instance, most image processing functions
+     * such as blurs, etc.).</p>
+     * <p>To properly process encoded RGB values you must first apply the
+     * EOTF to decode the value into linear space. After processing, the RGB
+     * value must be encoded back to non-linear ("gamma") space. Here is a
+     * formal description of the process, where \(f\) is the processing
+     * function to apply:</p>
+     *
+     * $$RGB_{out} = OETF(f(EOTF(RGB_{in})))$$
+     *
+     * <p class="note">Some RGB color spaces, such as {@link Named#ACES} and
+     * {@link Named#LINEAR_EXTENDED_SRGB scRGB}, are said to be linear because
+     * their transfer functions are the identity function: \(f(x) = x\).
+     * If the source and/or destination are known to be linear, it is not
+     * necessary to invoke the transfer functions.</p>
+     *
+     * <h3>Range</h3>
+     * <p>Most RGB color spaces allow RGB values in the range \([0..1]\). There
+     * are however a few RGB color spaces that allow much larger ranges. For
+     * instance, {@link Named#EXTENDED_SRGB scRGB} is used to manipulate the
+     * range \([-0.5..7.5]\) while {@link Named#ACES ACES} can be used throughout
+     * the range \([-65504, 65504]\).</p>

+     * </p>
+     *
+     * <h3>Converting between RGB color spaces</h3>
+     * <p>Conversion between two color spaces is achieved by using an intermediate
+     * color space called the profile connection space (PCS). The PCS used by
+     * this implementation is CIE XYZ. The conversion operation is defined
+     * as such:</p>
+     *
+     * $$RGB_{out} = OETF(T_{dst}^{-1} \cdot T_{src} \cdot EOTF(RGB_{in}))$$
+     *
+     * <p>Where \(T_{src}\) is the {@link #getTransform() RGB to XYZ transform}
+     * of the source color space and \(T_{dst}^{-1}\) the {@link #getInverseTransform()
+     * XYZ to RGB transform} of the destination color space.</p>
+     * <p>Many RGB color spaces commonly used with electronic devices use the
+     * standard illuminant {@link #ILLUMINANT_D65 D65}. Care must be take however
+     * when converting between two RGB color spaces if their white points do not
+     * match. This can be achieved by either calling
+     * {@link #adapt(ColorSpace, float[])} to adapt one or both color spaces to
+     * a single common white point. This can be achieved automatically by calling
+     * {@link ColorSpace#connect(ColorSpace, ColorSpace)}, which also handles
+     * non-RGB color spaces.</p>
+     * <p>To learn more about the white point adaptation process, refer to the
+     * documentation of {@link Adaptation}.</p>

+/**
+ * System API to the overall text services, which arbitrates interaction between applications
+ * and text services. You can retrieve an instance of this interface with
+ * {@link Context#getSystemService(String) Context.getSystemService()}.
+ *
+ * The user can change the current text services in Settings. And also applications can specify
+ * the target text services.
+ *
+ * <h3>Architecture Overview</h3>
+ *
+ * <p>There are three primary parties involved in the text services
+ * framework (TSF) architecture:</p>
+ *
+ * <ul>
+ * <li> The <strong>text services manager</strong> as expressed by this class
+ * is the central point of the system that manages interaction between all
+ * other parts.  It is expressed as the client-side API here which exists
+ * in each application context and communicates with a global system service
+ * that manages the interaction across all processes.
+ * <li> A <strong>text service</strong> implements a particular
+ * interaction model allowing the client application to retrieve information of text.
+ * The system binds to the current text service that is in use, causing it to be created and run.
+ * <li> Multiple <strong>client applications</strong> arbitrate with the text service
+ * manager for connections to text services.
+ * </ul>
+ *
+ * <h3>Text services sessions</h3>
+ * <ul>
+ * <li>The <strong>spell checker session</strong> is one of the text services.
+ * {@link android.view.textservice.SpellCheckerSession}</li>
+ * </ul>
