// PipelineStateOverride depthTestEnabled test.
// Two overlapping spheres: blue (closer, z=100) and red (farther, z=-100).
// Opaque objects are sorted front-to-back, so blue draws first, red draws second.
// With depthTestEnabled: false (no GPU depth test), the last-drawn object wins
// → red (drawn second) is visible at the center.
// With depthTestEnabled: true (default), the depth buffer keeps the closer object
// → blue (z=100, closer to camera at z=300) is visible at the center.
// The C++ test changes depthTestEnabled at runtime to verify the transition.
