mpfr_t	centery	Tile center (imaginary part).
int	col	Tile x coordinate (left is 0)
int	height	Tile height.
mpfr_t	radius	Tile radius.
int	row	Tile y coordinate (top is 0)
mpfr_t	tiled_centerx	Tiling center (real part).
mpfr_t	tiled_centery	Tiling center (imaginary part).

Initialize a tiling.

Parameters

tiling	The tiling to initialize.
cols	The number of tiles horizontally.
rows	The number of tiles vertically.
width	The image width of each tile in pixels.
height	The image height of each tile in pixels.
centerx	The real coordinate of the tiled view center.
