/**
 * The GpuLimitsSystem provides information about the capabilities and limitations of the underlying GPU.
 * These limits, such as the maximum number of textures that can be used in a shader
 * (`maxTextures`) or the maximum number of textures that can be batched together (`maxBatchableTextures`),
 * are determined by the specific graphics hardware and driver.
 *
 * The values for these limits are not available immediately upon instantiation of the class.
 * They are populated when the GL rendering context is successfully initialized and ready,
 * which occurs after the `renderer.init()` method has completed.
 * Attempting to access these properties before the context is ready will result in undefined or default values.
 *
 * This system allows the renderer to adapt its behavior and resource allocation strategies
 * to stay within the supported boundaries of the GPU, ensuring optimal performance and stability.
 * @example
 * ```ts
 * const renderer = new WebGlRenderer();
 * await renderer.init();
 *
 * console.log(renderer.limits.maxTextures);
 * ```
