The main purpose of the opengl testapp was to set the environment variable LIBGL_ALWAYS_INDIRECT if direct rendering is not supported before glx gets initialized. With Qt5 we may no longer set this environment variable. QtQuick requires direct rendering. On IvyBridge QtQuick is crashing if the variable is set. Thus we are no longer allowed to set it and thus the complete test becomes pointless. The test app basically whitelisted most drivers anyway, the only drivers which were problematic are the proprietary Catalyst drivers. It that's still a problem we can also disable OpenGL compositing on those drivers through the recommendation in the GLPlatform. This also means that the KWIN_DIRECT_GL variable is no longer useful.
