5ea143f521 Only skip moving the cursor if it is already in the last position _on
the same line_, fixes redraw bug reported by patrick keshishian.

9fc925ac51 When comparing ocy to orlower in tty_cmd_cell, there is no need to add
yoff (because they are both already relative to the pane). Also fix some
other minor nits.

ddf7ac5ae4 Fix calculation of whether we need a region for drawing a cell (only if
full width and at the edge of the region), otherwise clear the region entirely.

c34a79b152 Turn on margins, with a couple of fixes (only limit to the pane for line
feeds, and do not move cursor to end for full width panes).

0ace779cde Initial attempt to make use of left and right margins if the terminal
supports them (that is, if it advertises itself as a VT420 - probably
just xterm). These are the vertical equivalent of the scroll region and
allow much faster scrolling of panes that do not take up the full width
of the terminal.

d413a945ac Don't make assumptions about line wrap on !xenl terminals, means that
using a wrong TERM without xenl is not so broken if used on a sensible
terminal.

4179b42424 Add support for BCE (background colour erase). This makes various escape
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.

On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

Mostly written by Sean Haugh.

0f73af876f Don't update cells in each block of data read from a pane immediately,
instead track them as change (dirty) and update them once at the end,
saves much time if repeatedly writing the same cell. Also fix comparison
of cells being equal in a few places (memcmp is not enough).

7d105738b6 Send two cub1 instead of using cub for moving the cursor two left. This
is normally better because using cub1 will be ^H^H (so two bytes) but
cub would be ^[[2D (four).

bcb41a09b3 RGB colours shouldn't be mixed up with aixterm colours, return before
that happens when working out if they are supported.

427b820426 Support for RGB colour, using the extended cell mechanism to avoid
wasting unnecessary space. The 'Tc' flag must be set in the external
TERM entry (using terminal-overrides or a custom terminfo entry), if not
tmux will map to the closest of the 256 or 16 colour palettes.

Mostly from Suraj N Kurapati, based on a diff originally by someone else.

32e510bd70 Remove support for the UTF-8 mouse extension. This was a briefly used,
poor idea that was fairly quickly replaced by SGR mouse input (which is
now widespread). It is impossible to tell the difference between UTF-8
and non-UTF-8 mouse input; since the mouse-utf8 option was removed tmux
has not handled it correctly in any case; and it is ridiculous to have
three different forms of mouse input.

c5689a5a40 Long overdue change to the way we store cells in the grid: now, instead
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.

This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.

The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.

abb4e9e2fa The output log is only useful once and it means creating a file, so open
it once at startup instead of in every call to tty_open.

7382ba82c5 If default-terminal is set to "screen" or "screen-*", emulate screen's
historical (incorrect) behaviour for SGR 3 and send smso
(standout). Previously, we would send sitm (italics) if the terminal
outside had it and smso otherwise. This was acceptably until recently
because xterm's terminfo entry lacked sitm, so most users got smso.

People who want italics should set default-terminal to the forthcoming
"tmux" entry (and be prepared to deal with it being missing on older
hosts).

As a side-effect this changes default-terminal to be a server rather
than a session option.

bf635e7741 Rewrite of tmux mouse support which was a mess. Instead of having
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).

See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).

The default builtin bindings for the mouse are:

    bind -n   MouseDown1Pane select-pane -t=; send-keys -M
    bind -n MouseDown1Status select-window -t=
    bind -n   MouseDrag1Pane copy-mode -M
    bind -n MouseDrag1Border resize-pane -M

To get the effect of turning mode-mouse off, do:

    unbind -n MouseDrag1Pane
    unbind -temacs-copy MouseDrag1Pane

The old mouse options are now gone, set-option -q may be used to
suppress warnings if mixing configuration files.

4a7587931c Fix some issues in bright colour handling. Bold background doesn't exist
so there is no reason for tty_check_bg to mess with the BRIGHT flag at
all, ever. Also use aixterm colours for 256-to-16 translation if the
terminal supports them. And there is no reason for tty_colours_bg to
worry about whether the terminal supports them - tty_check_bg has
already taken care of it.
