- *
- * During a flush, this class assembles the accumulated draw data into a single vertex and texel
- * buffer, and its subclass draws the batches using backend-specific instanced rendering APIs.
- *
- * This class is responsible for the CPU side of instanced rendering. Shaders are implemented by
