matthieu 428261197a Upgrade to xorg-server 1.9.2. 
Tested by ajacoutot@, krw@, shadchin@ and jasper@ on various configurations
including multihead with both zaphod and xrandr.

/*
* BIGFONT extension for sharing font metrics between clients (if possible)
* and for transmitting font metrics to clients in a compressed form.
*
* Copyright (c) 1999-2000 Bruno Haible
* Copyright (c) 1999-2000 The XFree86 Project, Inc.
*/
/* THIS IS NOT AN X CONSORTIUM STANDARD */
/*
* Big fonts suffer from the following: All clients that have opened a
* font can access the complete glyph metrics array (the XFontStruct member
* `per_char') directly, without going through a macro. Moreover these
* glyph metrics are ink metrics, i.e. are not redundant even for a
* fixed-width font. For a Unicode font, the size of this array is 768 KB.
*
* Problems: 1. It eats a lot of memory in each client. 2. All this glyph
* metrics data is piped through the socket when the font is opened.
*
* This extension addresses these two problems for local clients, by using
* shared memory. It also addresses the second problem for non-local clients,
* by compressing the data before transmit by a factor of nearly 6.
*
* If you use this extension, your OS ought to nicely support shared memory.
* This means: Shared memory should be swappable to the swap, and the limits
* should be high enough (SHMMNI at least 64, SHMMAX at least 768 KB,
* SHMALL at least 48 MB). It is a plus if your OS allows shmat() calls
* on segments that have already been marked "removed", because it permits
* these segments to be cleaned up by the OS if the X server is killed with
* signal SIGKILL.
*
* This extension is transparently exploited by Xlib (functions XQueryFont,
* XLoadQueryFont).
