Scriptographer script for replicating existing objects in a block repeat pattern

How to use: run script, chose tiling parameters
(optional: make a "Tiles" layer, and do "generate Tiles"
select your objects and click "Assign Shapes"
Create an output layer and make it active
run "Replicate"
(optional, hide original shapes)

Hints for most regular results: (not that you need to want that!)
Place source objects in the bottom left tile.
Make the num of columns and the %drop multiply to an integer.
Make the num of rows and the %shift multiply to an integer.
Leave on of %shift or %drop equal to zero.
If using %drop, use even num rows.
If using %shift, use even number of columns.

Settings:
num_of_columns
num_of_rows
type_of_pattern: plain, pillar, strip, diaper
type_of_modification: none, h_mirror, v_mirror, rotate 180
drop_percent: 100% = one tile height
shift_percent: 100% = one tile width

max_random_translation: 0 (100% = one tile's worth)
max_random_rotation: 0 (100% = upside down)
min_random_scale: eg. 50%
max_random_scale: eg 250%

This script currently only works with Scriptographer 2.0.
