Return two functions, x(t) and y(t) that map the parameter t which must be
in the range [0, 1] to x and y co-ordinates in the cell. The rectcircle equation
in the range [0, 1] to x and y co-ordinates in the cell. The rectircle equation
we use is:
(|x| / a) ^ (2a / r) + (|y| / a) ^ (2b / r) = 1
where 2a = width, 2b = height and r is radius
The entire rectcircle fits in four cells, each cell being one quadrant
of the full rectcircle and the origin being the center of the rectcircle.
The entire rectircle fits in four cells, each cell being one quadrant
of the full rectircle and the origin being the center of the rectircle.
The functions we return do the mapping for the specified cell.
