<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Despite my code being clearly right this doesn't work. (according to apitrace and then qDebug)
oldState is always 0
This means we are binding textures every frame, which is what we wanted to avoid.
I'm quite confused as to why.</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 understand it now (I think)
If I have 2 icons, I will have 2 materials, but still only 1 shader.
oldState is used so that when SG batches operations I don't have to update all my uniforms if properties are the same between different materials being rendered in different nodes. It is not the previous state of the current material being updated.
Sorry for the noise.</pre>

This will save constantly uploading a new texture to OpenGL throughout the animation.</pre>
