// .SECTION Description
// A common interactor style for the ospray tests that understands
// the following key presses.
// c        => switch between OSPRay and GL
// s        => turn shadows on and off
// n        => focuses view on the next actor and hides all others
// 2/1      => increase/decrease the number of samples per pixel
// P/p      => increase/decrease the number of OSPRay rendering passes
// l        => turns on each light in the scene in turn
// I/i      => increase/decrease the global light intensity scale
// D/d      => increase/decrease the number of ambient occlusion samples
// t        => change renderer type: scivis, pathtracer
// N        => toggle use of openimage denoiser, if applicable
