Title: Any angle gradient (bonus: circular gradient)
Description: More gradients (last one, I hope): Now, 'any angle' gradient. // For fastest renderings, see my other post (Code ID: 60477; only for horizontal, vertical and both diagonals directions). // Last update Dec 13th, 2005: Improvements in circular gradient. SQR function completely avoided: using axis squares sum accumulators + squares sequence.
