Implement visualization in its own, separate thread #47
Description
The way the program currently works is that when visualization is enabled, each IK solving thread handles the visualization of its solved IK. This slows the thread down significantly when visualization is enabled.
A better solution could be to save the state to be visualized to a buffer and let a specialized visualizer thread read it from there and visualize it at its own pace, preferably only visualizing the latest state in the buffer whenever the previous visualization is complete.
