* There are buggy terminals out there that do not move the cursor to 0,0nicm2017-02-161-2/+2

* Collect sequences of printable ASCII characters and process themnicm2017-02-081-2/+12
| | | | | | | | | | | | | | | 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).

* Implement "all event" (1003) mouse mode but in a way that works. Thenicm2017-02-011-1/+6
| | | | | | | | | | | main issue is that if we have two panes, A with 1002 and B with 1003, we need to set 1003 outside tmux in order to get all the mouse events, but then we need to suppress the ones that pane A doesn't want. This is easy in SGR mouse mode, because buttons == 3 is only used for movement events (for other events the trailing m/M marks a release instead), but in normal mouse mode we can't tell so easily. So for that, look at the previous event instead - if it is drag+release as well, then the current event is a movement event.

| | | | | | | | | | | | 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.

* Support for RGB colour, using the extended cell mechanism to avoidnicm2016-01-291-15/+22
| | | | | | | | 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.

* Remove support for the UTF-8 mouse extension. This was a briefly used,nicm2015-11-231-7/+1
| | | | | | | | 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.

* Long overdue change to the way we store cells in the grid: now, insteadnicm2015-11-131-3/+3
| | | | | | | | | | | | | | | 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.
