TexDataArea Area Memory Map
u32 tex_img_width Width of texture image data to be used.
u32 tex_img_height Height of texture image data to be used.
u32 tex_tile_scale_num When TEX_ANIM_SCROLL_SCALE or TEX_ANIM_SCROLL_SCALE_KEY is specified, 'scaling animation' of the texture data is performed. 

When texture scaling animation is not performed, set the following flag.
TEX_TILE_SCALE_NONE     0x00000001

When key frame animation is performed, specify the number of the key.
u32 tex_tile_offset_num When TEX_ANIM_SCROLL_OFFSET or TEX_ANIM_SCROLL_OFFSET_KEY is specified, 'scrolling animation' of the texture data is performed. 

When texture scrolling animation is not performed, set the following flag.
TEX_TILE_OFFSET_NONE    0x00000001

When performing key frame animation, specify the number of the key.
u32 tex_tile_img_num When TEX_ANIM_FLIPBOOK or TEX_ANIM_FLIPBOOK_KEY is specified, it executes 'flip book animation' by switching the texture image.

When flip book animation is not executed, set the following flag.
TEX_FLIPBOOK_NONE       0x00000001

When key frame animation is not performed, specify the number of the key.
u32 tex_tile_scale_key Specifies the number of the key frame in a sequence when TEX_ANIM_SCROLL_SCALE_KEY is specified. Otherwise, the flag is ignored.
u32 tex_tile_width Specifies the width of the texture tile data.

If tex_tile_scale_num = TEX_TILE_SCALE_NONE, specify tex_tile_width(0) to use this area as static data storage.
u32 tex_tile_height Specifies the height of the texture tile data.

If tex_tile_scale_num = TEX_TILE_SCALE_NONE, specify tex_tile_height(0) to use this area as static data storage.
u32 tex_tile_offset_key Specifies the number of the key frame in a sequence when TEX_ANIM_SCROLL_OFFSET_KEY is specified. Otherwise, this flag is ignorned.
u32 tex_tile_offset_x Texture offset X coordinate of the upper left tile.

If tex_tile_offset_num = TEX_TILE_OFFSET_NONE, specify tex_tile_offset_x(0) to use this area as static data storage.
u32 tex_tile_offset_y Texture offset Y coordinate of the upper left tile.

If tex_tile_offset_num = TEX_TILE_OFFSET_NONE, specify tex_tile_offset_y(0) to use this area as static data storage.
u32 tex_tile_img_key Specifies the number of the key frame in a sequence when TEX_ANIM_FLIPBOOK_KEY is specified. Otherwise, this flag is ignored.
u32 tex_tile_img_index Index number of texture image data in TexImgList.

If tex_tile_img_num = TEX_FLIPBOOK_NONE, specify tex_tile_img_index(0) to use this area as static data storage.
