[Java-game-lib-cvs] LWJGL/src/java/org/lwjgl/util/generator ContextCapabilitiesGenerator.java,1.4,1.5 ContextGeneratorProcessorFactory.java,1.4,1.5

[Elias N. <eli...@us...>]

Update of /cvsroot/java-game-lib/LWJGL/src/java/org/lwjgl/util/generator
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv10785/src/java/org/lwjgl/util/generator

Modified Files:
	ContextCapabilitiesGenerator.java 
	ContextGeneratorProcessorFactory.java 
Log Message:
OpenGL: Made generated ContextCapabilities only try to load super class symbols if a sub class is supported. This avoids spurious 'Could not locate symbol' warnings in debug mode (glLoadProgramNV on ATI hardware)
