I've added a revised version of QuadMirror to jlb.ulb. QuadMirror2 is a transform that takes a rectangular block from a fractal layer and tiles the fractal evenly with the block, mirroring it both horizontally and vertically.

The user specifies the number of blocks in each direction, the center of the original block, and where the original block goes (unmirrored). Because of the mirroring, there are only four possibilities that give different results.

Here's an example for playing with, six by four blocks:
