Temporarily split some TextureIO-related classes into Java SE and Java

ME versions to be able to compile the majority of the TextureIO
package for Java ME / CDC / FP while waiting for full Java SE 5
classes on devices. Java ME ports have not been tested.

+/** <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.
