Justin,

It's every pixel.  One way to specify a minimum size would be to low-pass
filter the image before running facet orientation.  Try Process/FFT/Bandpass
Filter... and enter the minimum length in the box "Filter Small Structures
Up to."  The limit for large structures should be set to a size that is
larger than any feature you are interested in.
