He might of been inspired by the recent, although off-topic there as well, geometry discussion on cocoa-dev. Touching on for one thing NSBezierPath. I myself still have problems keeping track of what is graphics card accelerated and what is not. I thought CG actually was not. To get graphics card hardware acceleration you had to get into OpenGL. One of, the VM implementing it as hw acceleration which it used to for a time? Or through JOGL or GL4Java. Like I said my understanding of this isn't nailed down though so that could be wrong.
I was actually looking at some of this related to the recent Cocoa-dev thread myself. I started looking at Bezier path stuff and got off into line drawing optimizations. Line drawing speed was in actual point in fact a major java grumbling point on this same list. I was going to try out, with java, the Wu algorithm indicated on one page but that is shy some code in the listing. The other post of Craig's corrects this, so thanks. Anyhow, personal edification regarding graphics optimization might be another reason it is on-topic to a java list.
Also there is that java includes J2ME. I was looking at one use of Bresenham's line algorithm as a scanner for a J2ME asteroids game. They haven't got those little nano-bots putting the graphics cards into the PDA's and cell phones yet I guess.
So, without a context, Craig might of been a bit OT but there are contexts where this stuff definitely belongs on a java list.
