QGlContext needs porting to QOpenGLContext which is in Gui.
Then you don't need to link OpenGL directly</pre>

You never know what will be called afterwards and it might expect it's GL_TEXTURE0.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm confused.
I need to set the active texture /before/ I bind to it.
Otherwise everything breaks.
