The actuall code for avoiding/snapping starts in moveresize.c at line 
455 I think.

Basically I build ordered list of vertical and horizontal gridlines and 
assign gravities to each side of each grid line. Negative gravity 
signifies that no window should approach it closer then the modulus of 
gravity, while posititive gravity signifies distance from which window 
edge could be attracted to the gridline.

This thing is more complex due to the edge-snapping, and If I was doing 
just the strut/avoid cover thing I would go with the set of available 
rectangles and best-fit criteria.
