Print information about OpenGL or OpenGLES contexts
Description
This is a simple tool that prints information about OpenGL or OpenGLES
contexts. It is roughly comparable to glewinfo or glxinfo, with the
following differences:
- it uses Qt for platform abstraction
- it focusses on modern OpenGL
- it prints implementation limits such as GL_MAX_DRAW_BUFFERS
- it omits information about GLX and visuals
