Michael Grant 386799eef8 image: keep Kitty placements intact when a floating pane is dragged
Dragging a floating pane over a Kitty image left two kinds of damage.

A redraw marked every placement touching its area as stale and deleted it
whole, but only replaced the part inside the area, so the rest of the
image vanished and left holes behind the moved pane. kitty_redraw_start()
now places the parts outside the area again before the old placement is
deleted.

redraw_draw_damage_rect() only cleared placements in cells owned by a
pane, so a placement where the floating pane used to be, on cells now
belonging to its border, was never deleted and stayed drawn over it.
Clear placements under every span type except the status line.

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

Or open a GitHub issue or pull request.

* Documentation

For documentation on using tmux, see the tmux.1 manpage. View it from the
source tree with:

	$ nroff -mdoc tmux.1|less

A small example configuration is in example_tmux.conf.

Other documentation is available in the wiki:

For debugging, run tmux with -v and -vv to generate server and client log files
in the current directory.
