  * Return list of (and count of) all specific texture compression

  * formats that are supported.

  *

+ * Some formats are \b not returned by this function.  The

+ * \c GL_COMPRESSED_TEXTURE_FORMATS query only returns formats that are

+ * "suitable for general-purpose usage."  All texture compression extensions

+ * have taken this to mean either linear RGB or linear RGBA.

+ *

+ * The GL_ARB_texture_compress_rgtc spec says:

+ *

+ *    "19) Should the GL_NUM_COMPRESSED_TEXTURE_FORMATS and

+ *        GL_COMPRESSED_TEXTURE_FORMATS queries return the RGTC formats?

+ *

+ *        RESOLVED:  No.

+ *

+ *        The OpenGL 2.1 specification says "The only values returned

+ *        by this query [GL_COMPRESSED_TEXTURE_FORMATS"] are those

+ *        corresponding to formats suitable for general-purpose usage.

+ *        The renderer will not enumerate formats with restrictions that

+ *        need to be specifically understood prior to use."

+ *

+ *        Compressed textures with just red or red-green components are

+ *        not general-purpose so should not be returned by these queries

+ *        because they have restrictions.

+ *

+ *        Applications that seek to use the RGTC formats should do so

+ *        by looking for this extension's name in the string returned by

+ *        glGetString(GL_EXTENSIONS) rather than

+ *        what GL_NUM_COMPRESSED_TEXTURE_FORMATS and

+ *        GL_COMPRESSED_TEXTURE_FORMATS return."

+ *

+ * There is nearly identical wording in the GL_EXT_texture_compression_rgtc

+ * spec.

+ *

+ * The GL_EXT_texture_rRGB spec says:

+ *

+ *    "22) Should the new COMPRESSED_SRGB_* formats be listed in an

+ *        implementation's GL_COMPRESSED_TEXTURE_FORMATS list?

+ *

+ *        RESOLVED:  No.  Section 3.8.1 says formats listed by

+ *        GL_COMPRESSED_TEXTURE_FORMATS are "suitable for general-purpose

+ *        usage."  The non-linear distribution of red, green, and

+ *        blue for these sRGB compressed formats makes them not really

+ *        general-purpose."

+ *

+ * The GL_EXT_texture_compression_latc spec says:

+ *

+ *    "16) Should the GL_NUM_COMPRESSED_TEXTURE_FORMATS and

+ *        GL_COMPRESSED_TEXTURE_FORMATS queries return the LATC formats?

+ *

+ *        RESOLVED:  No.

+ *

+ *        The OpenGL 2.1 specification says "The only values returned

+ *        by this query [GL_COMPRESSED_TEXTURE_FORMATS"] are those

+ *        corresponding to formats suitable for general-purpose usage.

+ *        The renderer will not enumerate formats with restrictions that

+ *        need to be specifically understood prior to use."

+ *

+ *        Historically, OpenGL implementation have advertised the RGB and

+ *        RGBA versions of the S3TC extensions compressed format tokens

+ *        through this mechanism.

+ *

+ *        The specification is not sufficiently clear about what "suitable

+ *        for general-purpose usage" means.  Historically that seems to mean

+ *        unsigned RGB or unsigned RGBA.  The DXT1 format supporting alpha

+ *        (GL_COMPRESSED_RGBA_S3TC_DXT1_EXT) is not exposed in the list (at

+ *        least for NVIDIA drivers) because the alpha is always 1.0 expect

+ *        when it is 0.0 when RGB is required to be black.  NVIDIA's even

+ *        limits itself to true linear RGB or RGBA formats, specifically

+ *        not including EXT_texture_sRGB's sRGB S3TC compressed formats.

+ *

+ *        Adding luminance and luminance-alpha texture formats (and

+ *        certainly signed versions of luminance and luminance-alpha

+ *        formats!) invites potential comptaibility problems with old

+ *        applications using this mechanism since old applications are

+ *        unlikely to expect non-RGB or non-RGBA formats to be advertised

+ *        through this mechanism.  However no specific misinteractions

+ *        with old applications is known.

+ *

+ *        Applications that seek to use the LATC formats should do so

+ *        by looking for this extension's name in the string returned by

+ *        glGetString(GL_EXTENSIONS) rather than

+ *        what GL_NUM_COMPRESSED_TEXTURE_FORMATS and

+ *        GL_COMPRESSED_TEXTURE_FORMATS return."

+ *

+ * There is no formal spec for GL_ATI_texture_compression_3dc.  Since the

+ * formats added by this extension are luminance-alpha formats, it is

+ * reasonable to expect them to follow the same rules as

+ * GL_EXT_texture_compression_latc.  At the very least, Catalyst 11.6 does not

+ * expose the 3dc formats through this mechanism.

+ *

  * \param ctx  the GL context

  * \param formats  the resulting format list (may be NULL).

- * \param all  if true return all formats, even those with  some kind

- *             of restrictions/limitations (See GL_ARB_texture_compression

- *             spec for more info).

  *

  * \return number of formats.
