60 * Send a large image to the server.  If necessary, a buffer is allocated
61 * to hold the unpacked data that is copied from the clients memory.
62 *
63 * \param gc        Current GLX context
64 * \param compsize  Size, in bytes, of the image portion
65 * \param dim       Number of dimensions of the image
66 * \param width     Width of the image
67 * \param height    Height of the image, must be 1 for 1D images
68 * \param depth     Depth of the image, must be 1 for 1D or 2D images
69 * \param format    Format of the image
70 * \param type      Data type of the image
71 * \param src       Pointer to the image data
72 * \param pc        Pointer to end of the command header
73 * \param modes     Pointer to the pixel unpack data
74 *
75 * \todo
76 * Modify this function so that \c NULL images are sent using
77 * \c __glXSendLargeChunk instead of __glXSendLargeCommand.  Doing this
78 * will eliminate the need to allocate a buffer for that case.
