                                      03 - FLOAT_4: (4 IEEE Floats)
                                      04 - BYTE: * (1 DWORD w 4 8-bit fixed point values) (X = [7:0], Y = [15:8], Z = [23:16], W = [31:24])
                                      05 - D3DCOLOR: * (Same as BYTE except has X->Z,Z->X swap for D3D color def) (Z = [7:0], Y = [15:8], X = [23:16], W = [31:24])

                                      10 - FLOAT_8: (8 IEEE Floats) Sames as 2 FLOAT_4 but must use consecutive DST_VEC_LOC. Used to allow > 16 PSC for OGL path.
                                      11 - FLT16_2: (1 DWORD with 2 16-bit floating point values (SE5M10 exp bias of 15, supports denormalized numbers)) (X = [15:0], Y = [31:16], Z = 0.0, W = 1.0)

SKIP_DWORDS_0          7:4    0x0     The number of DWORDS to skip (discard) after
                                      processing the current element.
DST_VEC_LOC_0          12:8   0x0     The vector address in the input memory to write this
                                      element
LAST_VEC_0             13     0x0     If set, indicates the last vector of the current vertex
                                      stream
SIGNED_0               14     0x0     Determines whether fixed point data types are unsigned
                                      (0) or 2`s complement signed (1) data types. See
                                      NORMALIZE for complete description of affect
NORMALIZE_0            15     0x0     Determines whether the fixed to floating point
                                      conversion will normalize the value (i.e. fixed point
                                      value is all fractional bits) or not (i.e. fixed point value is
                                      all integer bits).
                                      This table describes the fixed to float conversion results
                                      SIGNED NORMALIZE FLT RANGE
                                      0 0 0.0 - (2^n - 1) (i.e. 8-bit -> 0.0 - 255.0)
                                      0 1 0.0 - 1.0
                                      1 0 -2^(n-1) - (2^(n-1) - 1) (i.e. 8-bit -> -128.0 - 127.0)
                                      1 1 -1.0 - 1.0
                                      where n is the number of bits in the associated fixed
                                      point value
                                      For signed, normalize conversion, since the fixed point
                                      range is not evenly distributed around 0, there are 3
                                      different methods supported by R300. See the
                                      VAP_PSC_SGN_NORM_CNTL description for details.
