6.1.2 Texture Coordinate
This is another 2D coordinate specified as S and T (S: horizontal, T:
vertical). Any integer in a range of ï512 to +511 can be used as the S and T
coordinates. The texture coordinate is correlated to the 2D coordinate of a
vertex. All vertices forming a polygon have correlated texture coordinates.
One texture style pattern can be applied to up to 256 × 256 pixels. The
applied texture size is set in the register. When the S and T coordinate
exceeds the maximum size of the texture style pattern, the repeat, cramp or
border color option is selected.
