Oh, for sure. That's why they're in there :-) Ditto for MiscPrimPlugin 
(which has some of the string comparison prims) and B2DPlugin is 
required due to the heavy use of gradients and stuff.

The above is close to the smallest set of plugins if you don't require 
I/O. If you do, you would definitely add SocketPlugin (which is on my 
shortlist for the Android VM).
