Texture / Tile Pattern
It is possible to use a pattern as direct color mode ( 16 bits / pixel) or indirect color mode ( 8
bits / pixel).
1 ) Direct color mode ( 16 bits / pixel)
This data format is described RGB as each 5 bit. Bit15 is used for alpha bit of stencil or stencil
blending. ( Only texture mapping)
