- * Manages display list compilation, caching, and playback.
- * Handles VBO-based display list emulation with command recording and batching.
- *
- * <p>This class is responsible for:
- * <ul>
- *   <li>Display list lifecycle (glNewList, glEndList, glCallList, glDeleteLists)</li>
- *   <li>Command recording and accumulation during compilation</li>
- *   <li>Building optimized (batched) and unoptimized (nested-safe) command lists</li>
- *   <li>Transform tracking and collapsing for optimal GL call counts</li>
- *   <li>Cache management for compiled display lists</li>
- * </ul>
- *
- * <h3>Architecture: Transform Collapsing</h3>
- * <p>The optimization strategy collapses consecutive MODELVIEW transforms into single MultMatrix
- * commands, emitting them at "barriers" (draws, CallList, exit). This approach:</p>
- * <ul>
- *   <li>Keeps vertices canonical (untransformed) in VBOs</li>
- *   <li>Properly handles nested display lists (CallList) - GL state is correct before sub-list</li>
- *   <li>Reduces GL calls (multiple transforms → one MultMatrix)</li>
- *   <li>Maintains proper Push/Pop stack semantics</li>
- * </ul>
- *
- * <h4>Transform Tracking State</h4>
- * <ul>
- *   <li><b>accumulated:</b> Total relative transform (what GL matrix should be)</li>
- *   <li><b>lastEmitted:</b> What we've emitted (what GL matrix is)</li>
- *   <li><b>stack:</b> Saved accumulated values at Push points</li>
- * </ul>
- *
- * <h4>Batching Strategy</h4>
- * <p>Format-based batching: All draws with the same vertex format share a single VBO via
- * {@link FormatBuffer}. Each draw's position within the VBO is tracked as a {@link DrawRange}.
- * Consecutive draws with the same transform are merged into single ranges. Transforms are
- * handled via delta-based emission using {@link TransformOptimizer}.</p>
- *
