6.4.4 Filtering
MB86290A supports two texture filtering modes: point filtering, and bi-linear
filtering.
Point filtering
This mode uses the texcel data specified by the (S, T) coordinate. The
nearest texcel in the texture pattern is chosen according to the calculated (S,
T) coordinate.

Bi-linear filtering
This mode picks the four nearest texcels from the calculated (S, T)
coordinate. The color is blended and the texcel image is defined according to
the distance between each of these texcels and the calculated (S, T)
coordinate.
Note: This mode can be used when the internal memory is specified as the
texture memory mode.
