Prism and Quantum Toolkit

Prism renders things. It was optimized a lot over the course of JavaFX releases. Now, it uses hardware acceleration and software libraries available in the system such as DirectX or OpenGL. Also, Prism renders concurrently and also can render upcoming frames in advance while current frames are being shown, which gives a large performance advantage.

Quantum Toolkit manages the preceding Prism, Glass, and JavaFX API and handles events and rendering threads.
