Displays two cubes floating around each other on a multisampled surface. Tests multisampled depth buffers.
**MSAACube**
Same as RenderTextureCube, but with MSAA cube RTs. Draws triangles to each cubemap face so there's something to see. Tests cube render target MSAA.
**WindowResizing**
Tests resizing the window to various resolutions.
