Run any demo application (SwingSet2, Notepad, Java2Demo, etc) with the
-Dsun.java2d.opengl=true system property. When XAWT is used (by default on
Linux), top-level windows can be resized and everything looks fine. When
MAWT is used (by default on Solaris), top-level windows do not repaint properly
when resized.

It appears that with XAWT, GLXSurfaceData objects are recreated when the
window is resized, which causes the OGLSDOps width/height fields to be
properly reinitialized. In the MAWT case, it looks like the GLXSurfaceData
object for the window is not recreated, and therefore the width/height fields
are not reinitialized.
