set
fun set(program: SurfaceTextureProgram?, textureSector: Sector, opacity: Float, texture: Texture, texCoordMatrix: Matrix3, offset: Globe.Offset, terrainSector: Sector = textureSector): DrawableSurfaceTexture
texCoordMatrix must be axis-aligned affine (scale + translation, e.g. a vertical flip); the composite pack ignores rotation and shear terms.
