	cf Bug 83285 â Treacle-slow scrolling in gnome-terminal on unaccelerated X server

	Another chunk of performance improvements - the majority focussing on
	reducing the amount of work down per interrupt (input data from
	child).

	To handle reads without addition copies VTE_INPUT_CHUNK_SIZE chunks
	are allocated on demand and filled from read with no further copy -
	previously the read was into a local buffer and then immediately
	copied into a _vte_buffer.
	_vte_iso2022_process() is then adjusted to use a ptr+length, rather
	than a _vte_buffer and is called for every input chunk (taking special
	care over the boundary cases).
