      This extensions contains functions for loading and saving
      <keyword>Direct3D</keyword> textures
      using Imaging and for converting images to textures and vice versa.
      Currently supported <keyword>Direct3D</keyword> version is 9.0.
      You need <keyword>Direct3D</keyword> headers for
      <keyword>Object Pascal</keyword> to be able to compile this extension.
      They can be found at <link url="http://www.clootie.ru">http://www.clootie.ru</link>.
      Extension does not require D3DX library so if you use it
      only for loading or saving textures you can replace it by Imaging
      and remove dependency on 2+ MiB dll file.
      It is implemented in <ref>ImagingDirect3D9.pas</ref> unit located
      in <keyword>(ImagingRoot)\Source\Extensions</keyword> directory.
      To use it simply add this unit to <icode>uses</icode> list of your program.

      Here is the table with <keyword>Direct3D</keyword> functions
      currently available.
      There is also Imaging <keyword>Direct3D</keyword> demo you can look at
      for inspiration <link url="../Demos/Pascal.xml#d3ddemo">Object Pascal Direct3D Demo</link>.

    <note>
      <ref>LoadD3DTextureFromFile</ref> and similar functions use
      these default values: All mipmap levels are created, Pool
      is D3DPOOL_MANAGED, Usage is 0, Format and size are taken from image.
      If you want to set those parameters to other values use
      <ref>CreateD3DTextureFromImage</ref> or <ref>CreateD3DTextureFromMultiImage</ref>
      instead.
