 * The TextureUploadHandler receives textures uploads in the DMA chain and updates the TexturePool.
 * It will attempt to cache textures when possible as converting and uploading them to the GPU is
 * pretty expensive.
 *
 * Note that the PC Port sends a somewhat simplified texture upload message and this can't handle
 * any arbitrary PS2 texture transfer.  We rely on the texture metadata in GOAL to simplify this.
