e3359f8349 Some minor performance improvements - most notably, don't search the
input state table if the next character matches the same state as before.

58bbce09e2 Remove check for same size - size has already been changed so this

b89f2f28bb Fix grid clear code to correctly clear with the default background
colour rather than ending up with the used count higher than the total

b2bc34af12 Set a flag on cells are genuinely empty (cleared and never written to)
and use tty_clear_line (which will choose the best escape sequence) to
clear any batches of cells with that flag when redrawing a line from the
stored screen.

fc41bf46ac Add a "terminal" colour which can be used instead of "default" in style
options for the terminal default colour, bypassing any inheritance from
other options. Prompted by a discussion with abieber@.

enabled by adding the Smulx capability with terminal-overrides (add
something like ',vte*:Smulx=\E[4\:%p1%dm'). GitHub issue 1492.

ba31d3a88c Increment the lines counter when skipping a line to avoid an infinite
loop, and fix a check to avoid a potential out-of-bounds access. Problem
reported by Yuxiang Qin and tracked down by Karl Beldan; GitHub issue
1352.

Also a man page fix request by jmc@.

320abba341 Reflowing the grid in-place involved way too much memmove() for a big
performance cost with a large history. Instead change back to using a
second grid and copying modified lines over which is much faster (this
doesn't revert to the old code however which didn't support UTF-8
properly). GitHub issue 1249.

70bc07a358 Previously, extended cell data was never reduced in size even when the
cell was overwritten. With a large history this can be a substantial
amount of memory. To reduce this, compact each extended cell list to
only cells in use as it is scrolled off the visible screen into the
history. From Dan Aloni in GitHub issue 1062.

6abfd9b8ff Instead of overloading the line clear function to mean free if
background is default (8), introduce an explicit free function and use
it where a free alone is needed. Likewise, use memmove directly rather
than grid_move_lines where it makes sense. Based on a memory leak fix by
Dan Aloni in GitHub issue 1051.

0cd74723e1 When expanding a line in order to clear it, we need to use the default
background colour - there may be portions that we do not want to clear

03d01eabb5 When we write out the grid including escape sequences, an SGR 0 needs to
cause the colours to be written again. Also treat colours separately
from attributes so that RGB colours will work.

df3ab87964 Add support for the strikethrough attribute (SGR 9), using the new smxx
terminfo capability. This means there are now nine attribute bits, so
anything above 0xff uses an extended cell.

13a0b6bb3f Collect sequences of printable ASCII characters and process them
together instead of handling them one by one. This is significantly
faster. Sequences are terminated when we reach the end of the line, fill
the internal buffer, or a different character is seen by the input
parser (an escape sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).

nicm
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.

2627ab322e Remember the number of lines scrolled into the history (versus cleared

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).

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.
