 				Returns a new [PackedByteArray] with the data decompressed. Set the compression mode using one of [enum File.CompressionMode]'s constants. [b]This method only accepts gzip and deflate compression modes.[/b]
-				This method is potentially slower than [code]decompress[/code], as it may have to re-allocate it's output buffer multiple times while decompressing, where as [code]decompress[/code] knows it's output buffer size from the begining.
-
-				GZIP has a maximal compression ratio of 1032:1, meaning it's very possible for a small compressed payload to decompress to a potentially very large output. To guard against this, you may provide a maximum size this function is allowed to allocate in bytes via [code]max_output_size[/code]. Passing -1 will allow for unbounded output. If any positive value is passed, and the decompression exceeds that ammount in bytes, then an error will be returned.
