KetraTermacceptUntilGraphics
Consumes through the first graphics command requiring external decoding. Other commands dispatch synchronously. A yielded command has not reached the sink; consume it before supplying further bytes, including an empty range.
Return

Parameters
bytes
borrowed ingress storage, unchanged by parsing.
offset
first byte of the selected range.
length
number of bytes available from offset.
Throws
if the range is outside bytes.
if a previous payload is pending or the parser is reentered.
