From 006acbb9463af33a8b45aa0b3a298604eba72d82 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 21 Jun 2008 02:33:51 +0000 Subject: 2nd big refactoring. Goals are orthogonal components for: - OS Windowing system - NEWT, X11, Windows, MacOsX - GL Windowing GLUE - EGL, GLX, WGL, CGL - GL profiles - core and util packages - generate all Java components from any platform All above goals are achieved.
