    Description

      Commit bf5c25c4e75... against qglextensions.cpp changed the behaviour of QGLShader::hasOpenGLShaders on OpenGL1.x environments.

      With an Atom-based netbook running Ubuntu 10.04 support OpenGL 1.4 and GL_ARB_shading_language_120 this caused shader based programs to fail when they had run normally prior to that commit.
