44 * This macro defines the (many) parameters to the texstore functions.
45 * \param dims either 1 or 2 or 3
46 * \param baseInternalFormat user-specified base internal format
47 * \param dstFormat destination Mesa texture format
48 * \param dstX/Y/Zoffset destination x/y/z offset (ala TexSubImage), in texels
49 * \param dstRowStride destination image row stride, in bytes
50 * \param dstSlices array of addresses of image slices (for 3D, array texture)
51 * \param srcWidth/Height/Depth source image size, in pixels
52 * \param srcFormat incoming image format
53 * \param srcType incoming image data type
54 * \param srcAddr source image address
55 * \param srcPacking source image packing parameters
