Texture mapping
MB86R02 'Jade-D' supports texture mapping to map an image pattern onto the surface of plane.
The texture pattern can be laid out in the graphics memory. In this case, max. 4096 × 4096 pixels
can be used.
For drawing 8-bit color, only point sampling can be specified for texture interpolation; only decal
can be specified for the blend mode.

Caution: Use perspective correct mode when use texture at the top-left rule non-applicable mode.
Top-left rule non-applicable primitives cannot use geometry clip function.
Non-top-left-part's pixel quality is less than body (using approximate calculation)
