What generates colossal 1.4G /usr/share/icons/

[Fergus]

My preferred version of Cygwin is rather sparse, being
Base + a few additions from Utilities + gcc + latex + gnuplot + various minor for Cygwin-X.
Recently my footprint grew by much more than 1G.
What is it that generates the **absolutely massive** /usr/share/icons/?
I've had a hunt through "requires:" in setup.ini but got lost.  
Thank you!
Fergus
