 The function would be faster than ST_Intersection as it would not make any
 expensive effort at ensuring the output is valid (robustness issues would
 be expected to be tolerated by caller).
 Also it would accept invalid inputs.

 The function would also be specifically optimized for clipping with a
 rectangle, common in visualization (web, desktop).

 Upcoming GEOS 3.5.0 has a GEOSClipByRect function exposed for this:
