Short description of error

When exporting an animation in collada .dae format, I have set the the transforms to be matrix. But there are some cases in nodes, where rotation, scale and translate are still present. Should it all be a matrix per export setting?

For instance, the node Cylinder still has translate, rotate and scale. But I would expect this should be consolidated into a matrix but it is not. In the export settings, the transform type was set to Matrix not "TransLocRot". Should that be "TransRotScale"? You can see the Camera and Light nodes are matrix but not the cylinder node. So, it appears the file export is inconsistent.

Exact steps for others to reproduce the error

Export a file in .dae Collada format. "Includes animations" should be checked and "Samples" button selected. Make sure under the Anim tab that "Transformation Type" is set to "Matrix".

Based on the default startup or an attached .blend file (as simple as possible).

The exported file is attached. Nothing spectacular.

There is another bug related to this. If you set the export settings to enable translate, scale and rotate ( the TransLocRot option ), then it produces them only for node type="NODE". Otherwise, for node type="JOINT", the export still creates a matrix. Just feedback.
