.x meshloader regards now AnimTicksPerSecond (thx @qian for a test-model and bugreport).
CAnimatedMeshSceneNode::setMesh had commented-out the setAnimationSpeed line in version r3526 which was about a joint-cache fix for skinned meshes. But there was no comment about why that line had to be removed or commented out, so my guess is that this was only a test (I hope). And it caused animation-speed values for the meshes to be ignored unless user specified it explicitly while animation range was still changed in setMesh.
