OpenGL: Add code generator for OpenGL enabler classes This patch provides a code generator that can be executed offline to generate a few classes for enhancing Qt's support for OpenGL. The generated code effectively provides all the benefits of GLEW in its multi-context form but for all platforms and even for ES2. The code generator takes as input the official Khronos gl.spec specification and gl.tm typemap files. These provide all of the information required to create the OpenGL Desktop related classes. The classes for ES2 are hand-crafted as no similar spec files have been published. The generated code supports all OpenGL extensions listed in the Khronos registry for both Desktop OpenGL and ES 2. There is a helper factory class generated which are used by QOpenGLContext::versionFunctions(). This allows code like the following to be written: QOpenGLFunctions_3_3_Core* m_funcs = 0; m_funcs = m_context->versionFunctions<QOpenGLFunctions_3_3_Core>(); if (!m_funcs) { qWarning() << "Could not obtain required OpenGL context version"; exit(1); } if (!m_funcs->initializeOpenGLFunctions()) { qWarning() << "Failed to resolve entry points"; exit(2); } // Get an extension object QOpenGLExtension_ARB_draw_buffers* ext = 0; if (m_context->hasExtension("GL_ARB_draw_buffers")) { ext = new QOpenGLExtension_ARB_draw_buffers(); ext->initializeOpenGLFunctions(m_context); } Such usage will allow much easier and rigorous use of features in modern OpenGL and extensions both in Qt itself and by users of Qt. Follow-up patches will import the generated files and then use these to reinstate OpenGL geometry shaders, add tessellation shaders, and other OpenGL constructs.

QT -= gui
Fix build of util/glgen Don't use QSet::toList(), and fix an obvious typo. Also, core5compat is now needed due to the use of QRegExp. Change-Id: I766455996c07d354e97a4ed4939f1774fc449331 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>
