Nicholas Marriott 8ff65230e1 Optimize sixel_print. Previously, the algorithm scanned each pixel several 
times; once to find out which colors are active, and then once for every single
active color to actually construct the output string.

Now it constructs the compressed sixel patterns in the first pass (now x * 12
iters), so we can reduce the second pass (the really expensive part, at active
colors * x * 6 iters) to just appending these to the output buffer.

README 

Welcome to tmux!

tmux is a terminal multiplexer: it enables a number of terminals to be created,
accessed, and controlled from a single screen. tmux may be detached from a
screen and continue running in the background, then later reattached.

This release runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS and Solaris.

* Dependencies

tmux depends on libevent 2.x, available from:

	https://github.com/libevent/libevent/releases/latest

It also depends on ncurses, available from:

	https://invisible-mirror.net/archives/ncurses/

To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a
suitable yacc (yacc or bison) are needed.

* Installation

To build and install tmux from a release tarball, use:

	$ ./configure && make
	$ sudo make install

tmux can use the utempter library to update utmp(5), if it is installed - run
configure with --enable-utempter to enable this.

To get and build the latest from version control - note that this requires
autoconf, automake and pkg-config:

	$ git clone https://github.com/tmux/tmux.git
	$ cd tmux
	$ sh autogen.sh
	$ ./configure && make
	$ sudo make install

* Contributing

Bug reports, feature suggestions and especially code contributions are most
welcome. Please send by email to:

	tmux-users@googlegroups.com
