+/** <P> Provides input and output facilities for both loading OpenGL
+ textures from disk and streams as well as writing textures already
+ in memory back to disk. </P>
+
+ <P> The TextureIO class supports an arbitrary number of plug-in
+ readers and writers via TextureProviders and TextureWriters.
+ TextureProviders know how to produce TextureData objects from
+ files, InputStreams and URLs. TextureWriters know how to write
+ TextureData objects to disk in various file formats. The
+ TextureData class represents the raw data of the texture before it
+ has been converted to an OpenGL texture object. The Texture class
+ represents the OpenGL texture object and provides easy facilities
+ for using the texture. </P>
+
+ <P> There are several built-in TextureProviders and TextureWriters
+ supplied with the TextureIO implementation. The most basic
+ provider uses the platform's Image I/O facilities to read in a
+ BufferedImage and convert it to a texture. This is the baseline
+ provider and is registered so that it is the last one consulted.
+ All others are asked first to open a given file. </P>
+
+ <P> There are three other providers registered by default as of
+ the time of this writing. One handles SGI RGB (".sgi", ".rgb")
+ images from both files and streams. One handles DirectDraw Surface
+ (".dds") images read from files, though can not read these images
+ from streams. One handles Targa (".tga") images read from both
+ files and streams. These providers are executed in an arbitrary
+ order. Some of these providers require the file's suffix to either
+ be specified via the newTextureData methods or for the file to be
+ named with the appropriate suffix. In general a file suffix should
+ be provided to the newTexture and newTextureData methods if at all
+ possible. </P>
+
+ <P> Note that additional TextureProviders, if reading images from
+ InputStreams, must use the mark()/reset() methods on InputStream
+ when probing for e.g. magic numbers at the head of the file to
+ make sure not to disturb the state of the InputStream for
+ downstream TextureProviders. </P>
+
+ <P> There are analogous TextureWriters provided for writing
+ textures back to disk if desired. As of this writing, there are
+ four TextureWriters registered by default: one for Targa files,
+ one for SGI RGB files, one for DirectDraw surface (.dds) files,
+ and one for ImageIO-supplied formats such as .jpg and .png. Some
+ of these writers have certain limitations such as only being able
+ to write out textures stored in GL_RGB or GL_RGBA format. The DDS
+ writer supports fetching and writing to disk of texture data in
+ DXTn compressed format. Whether this will occur is dependent on
+ whether the texture's internal format is one of the DXTn
+ compressed formats and whether the target file is .dds format.
