Added Depth-of-Field rendering to SparkRenderer, controlled by two to parameters
focalDistance(distance to focal plane) andapertureAngle(full view angle subtended by aperture / circle of confusion).Added an examples/depth-of-field to showcase how to use it (including reasonable values).
Note that this is not a physically correct depth of field effect, but a trick with Gsplats where we can convolve it with a Gaussian equal in size to the circle of confusion at that projection plane. The result is fairly convincing and easy to integrate. Large focus blurs will incur overhead during rendering, so use judiciously.
