Glitchy1
* Mix of lazysensen and pixel flow by bezo97, https://bezo97.tk/plugins.html
* Variables added by Brad Stefanov and Rick Sidwell and special thanks to
* dark-beam
info on variables – from Rick Sidwell
scale_x, scale_y, and scale_z are the scales of the lazysensen swapping for each axis, same as lazysensen.
shift_x, shift_y, and shift_z are the offsets of the lazysensen swapping
n_x, n_y, and n_z are the swap counts; it swaps every n strips (2 for lazysensen behavior)
width controls the size of the shards; larger values make smaller pieces
seed is for the random number generator; change to create different patterns
angle is the sharding angle, in degrees
u, v, and w control the shard randomization in three angles
