What problem does it solve?

Add stencil buffer testing to an SDL GPU project to enable per-pixel masking, portals, and outlines in real-time graphics.

Core Features & Use Cases

• Depth-stencil texture setup with stencil bits (e.g., D24_UNORM_S8_UINT) to enable stencil operations.
• Pipeline state configuration to enable front and back stencil tests and per-draw stencil references.
• Implement portal rendering by masking and revealing alternate scenes through the stencil mask.
• Create object outlines and masked overlays using stencil tests for selective rendering.

Quick Start

Enable stencil testing in your SDL GPU project by creating a depth-stencil texture with stencil bits and wiring up the stencil states, then render a simple portal example to verify masking.
