	cf Bug 399617 â Avoid memory allocations during an expose event.

	Currently we cannot generate long glyph runs due to the text
	painting being broken up into single rows and setting a low
	max run cap. The benefit of longer runs is the backends can
	do more caching within a run and potentially generate fewer
	render calls and/or less network traffic.

	In the simple test case, this increased the performance of a
	remote hexdump by 10%.

	* src/vte.c: (vte_terminal_draw_rows), (vte_terminal_paint):
		Scan entired exposed area for glyph runs.
	* src/vtedraw.h:
		Increase VTE_DRAW_MAX_LENGTH
	* src/vtexft.c: (_vte_xft_draw_text):
		Create GlyphSpecs rather than CharFontSpecs, saves a 
		conversion and potential malloc inside libXft, and our
		own malloc.
