<summary>
Creates an alpha texture of the specified type.
</summary>
<param name="textureType">Specifies the type of texture requested. If a bi-level texture is requested, the
texture contains only bi-level glyphs. Otherwise, the texture contains only anti-aliased glyphs.</param>
<param name="textureBounds">Specifies the bounding rectangle of the texture, which can be different than
the bounding rectangle returned by GetAlphaTextureBounds.</param>
<param name="alphaValues">Receives the array of alpha values.</param>
<param name="bufferSize">Size of the alphaValues array. The minimum size depends on the dimensions of the
rectangle and the type of texture requested.</param>
<returns>
Standard HRESULT error code.
