From ee843ac7077f5dcae677ad1b7c794abb0b89e111 Mon Sep 17 00:00:00 2001
From: Keith Packard <keithp@guitar.keithp.com>

Subject: Add mode origins and output options.

Mode origins indicate the source of the mode information, from VESA timings,
user config or whatever.

Output options currently include only panel fitting options; more may be
added later (this field is 32 bits wide)
