[Java-game-lib-cvs] LWJGL/src/native/linux org_lwjgl_opengl_LinuxContextImplementation.c,1.6,1.7

Update of /cvsroot/java-game-lib/LWJGL/src/native/linux
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv9998

Modified Files:
	org_lwjgl_opengl_LinuxContextImplementation.c 
Log Message:
Linux: Removed the glXIsDirect test to determine whether a context is accelerated or not. This is specifically not the case for Xgl and friends that accelerates indireect rendering. Unfortunately, I'm not sure what to replace the test with, so there is currently no way to know from LWJGL whether we're software rendered or not (other than measuring FPS). In fact, I'm not even sure that we can come up with a good test, because some (DRI) drivers use software MESA rendering for some parts of GL, while other parts are hardware accelerated
