Remarks

• The MeshManager is responsible for grouping meshes into batches for efficient GPU upload and rendering.
• Meshes are organized by primitive type and managed in batches to minimize draw calls and optimize memory usage.
• The manager coordinates with GPUMemoryManager to allocate, update, and release GPU memory for mesh data.
• Mesh handles and batch handles provide references for updating mesh attributes, visibility, and rendering state.
• Used internally by the renderer; not typically accessed directly by application code.

Key Classes

• MeshManager: Main batching and management class for meshes.
• MeshBatch: Interface for a batch of meshes with the same primitive type.
• MeshBatchMeshHandle: Handle for referencing a mesh within a batch.
• RendererMesh, RendererGeometry, RendererTexture, RendererTextureSet: Internal representations of mesh, geometry, and texture data.
