2005-04-11 Karl Runge <runge@karlrunge.com>
* fix -clip under -rawfb, fix offset bug under file lseeking.
* add -rawfb setup:cmd mode to initialize fb.
2005-04-10 Karl Runge <runge@karlrunge.com>
* -rawfb non X-polling (i.e. shm, mmap, lseek).
* -pipeinput enable external user input processing command.

If string is "setup:cmd", then the command "cmd"
is run and the first line from it is read and used
as \fIstring\fR. This allows initializing the device,
determining WxHxB, etc. These are often done as root
so take care.

Optional suffixes are ":R/G/B" and "+O" to specify
red, green, and blue masks and an offset into the

Another experimental option: it lets you supply an
extern command in \fIcmd\fR that x11vnc will pipe all of
the user input events to in a simple format. By default
x11vnc will not process any of the user input events.
If you prefix \fIcmd\fR with "tee:" it will both send
them to the pipe command and process them. For a
description of the format run "\fB-pipeinput\fR \fItee:cat\fR".
Another prefix is "reopen" which means to reopen pipe
if it exits. Separate multiple prefixes with commas.
