not get a problem with calculating the precise pixel coordinates


no because worst case 32 bit floating point precision between 0.0 and 1.0 is 1 / 16,777,216 (between 0.5 and 1.0)
and I only need precision down to 1 / 16,384 to hit the centroids

no because worst case 32 bit floating point precision between 0.0 and 1.0 is 23 bits = 1 / 8,388,608
and I only need precision down to 1 / 16,384 to hit the centroids
