+ * called immediately when the object is created before it is passed to another thread.
+ * No thread safety is required.
+ *
+ * For instance, imagine if we have this interface:
+ *     interface IFoo { void doFoo(); }
+ *
+ * A). Historical option that has proven to be BAD! Only the original
+ *     author of an interface should change an interface. If someone

+ *     change the interface or use this method.
+ *
+ *    BAD TO DO:  interface IFoo {                       BAD TO DO
+ *    BAD TO DO:      void doFoo();                      BAD TO DO

+ *
+ * B). Option that this method enables.
+ *     Leave the original interface unchanged (do not change IFoo!).
+ *     Instead, create a new interface in a downstream package:
+ *
+ *         package com.<name>; // new functionality in a new package
+ *         interface IBar { void doBar(); }
+ *
+ *     When registering the interface, add:
+ *         std::shared_ptr<MyFoo> foo = new MyFoo; // class in AOSP codebase
+ *         std::shared_ptr<MyBar> bar = new MyBar; // custom extension class
+ *         ... = AIBinder_setExtension(foo->asBinder().get(), bar->asBinder().get());
+ *         // handle error
+ *
+ *     Then, clients of IFoo can get this extension:
+ *         SpAIBinder binder = ...;
+ *         std::shared_ptr<IFoo> foo = IFoo::fromBinder(binder); // handle if null
+ *         SpAIBinder barBinder;

+ *         // type is checked with AIBinder_associateClass

- * Decode a DXT-compressed texture into memory.  DXT textures consist of
- * a series of 4x4 pixel blocks in left-to-right, top-down order.
- * The number of blocks is given by ceil(width/4)*ceil(height/4).
- *
- * 'data' points to the texture data. 'width' and 'height' indicate the
- * dimensions of the texture.  We assume width and height are >= 0 but
- * do not require them to be powers of 2 or divisible by any factor.
- *
- * The output is written to 'surface' with each scanline separated by
- * 'stride' 2- or 4-byte words.
- *
- * 'format' indicates the type of compression and must be one of the following:
- *
- *   GL_COMPRESSED_RGB_S3TC_DXT1_EXT:
- *      The output is written as 5/6/5 opaque RGB (16 bit words).
- *      8 bytes are read from 'data' for each block.
- *
- *   GL_COMPRESSED_RGBA_S3TC_DXT1_EXT
- *      The output is written as 5/5/5/1 RGBA (16 bit words)
- *      8 bytes are read from 'data' for each block.
- *
- *   GL_COMPRESSED_RGBA_S3TC_DXT3_EXT
- *   GL_COMPRESSED_RGBA_S3TC_DXT5_EXT
