The window decorations can be disabled as of 1.4 and above; see
the sources for the Grand Canyon demo
(http://java.sun.com/products/jfc/tsc/articles/jcanyon/) for an
example. I spent some time in the 1.4 timeframe trying to
understand exactly what Windows API calls go into making a
full-screen window which is compatible with OpenGL; this is the
underlying implementation of full-screen when
-Dsun.java2d.noddraw=true is specified. However, I believe there
are still problems with this implementation though I haven't had
time to look into them. If you or anyone else can write a small,
self-contained C/C++ program on Windows (not using GLUT) which
makes a full-screen OpenGL window and draws a triangle into it,
I'll try to get the non-DirectDraw full-screen implementation
fixed in the JDK.

FYI, the SCSL sources for 1.4 are available on Sun's web site, so
you can look at the current full-screen implementation.
