25 September 2008
* Large internal rewrite to better support 256 colours and UTF-8. Screen data
is now stored as single two-way array of structures rather than as multiple
separate arrays. Also simplified a lot of code.
Only external changes are three new flags, -2, -d and -u, which force tmux to
assume the terminal supports 256 colours, default colours (useful for
xterm-256color which lacks the AX flag), or UTF-8 respectively.
10 September 2008
* Split off colour conversion code from screen code.

XXX
screen contains grid
screen_write <-- write to TTY and to screen using close-to-ANSI functions
screen_redraw <-- write areas of screen to TTY
grid_view <-- write to viewable area of grid
grid <-- manipulate grid and history
XXX
grid_view has ox,oy

- FINISH UTF8: fix copy and paste
- SPLIT u_short attr into attr,flags?
- maybe rethink backend data structure?
- utf8 can be 1-4 bytes
- most common is 1 bytes
- there can be double-width characters which take n bytes but 2 columns on screen
- they are not only drawn as two characters, they also require two backspaces to remove
- three operations:
- simultaneously update screen and ttys
- redraw screen or section of screen to ttys
- write to ttys without updating screen
---
NEED to be able to:
resize screen
apply ops to both screen and tty simultaneously
both when parsing input and when eg scrolling history
draw on the top of the screen without modifying it
display arbitrary parts of the history
redraw arbitrary parts of the visible screen
---
NEVER need to draw into the history
split off grid manip:
16-bit characters
8-bit flags
8-bit attributes
8-bit fg colour
8-bit bg colour

---
screen has two (both grid_view):
base and overlay
---
screen_write writes into overlay if it exists and then base, also optionally to tty
screen_draw draws overlay + base to display
---
---
Would it be better to just expand char to 16-bits and use it as an index only
for >2-byte characters? or - better - don't support entire UTF range? only the BMP?
this would get rid of UTF table and limits, but still leave double-width character annoyances
also would double memory usage
TODO -- 2 fix window-*.c
3 resizing
4 audit for leftover/unused code
5 next phase of tidying

/*
* Virtual screen.
*
* A screen is stored as three arrays of lines of 8-bit values, one for the
* actual characters (data), one for attributes and one for colours. Three
* seperate blocks means memset and friends can be used. Each array is y by x
* in size, row then column order. Sizes are 0-based. There is an additional
* array of u_ints with the size of each line.
*
* Each screen has a history starting at the beginning of the arrays and
* extending for hsize lines. Beyond that is the screen display of size
* dy:
*
* ----------- array base
* | |
* | history |
* ----------- array base + hsize
* | |
* | display |
* | |
* ----------- array base + hsize + dy
*
* The screen_x/screen_y macros are used to convert a cell on the displayed
* area to an absolute position in the arrays.
*
* Screen handling code is split into four files:
*
* screen.c: Creation/deletion, utility functions, and basic functions to
* manipulate the screen based on offsets from the base.
* screen-display.c: Basic functions for manipulating the displayed
* part of the screen. x,y coordinates passed to these
* are relative to the display. These are largely
* utility functions for screen-write.c.
* screen-redraw.c: Functions for redrawing all or part of a screen to
* one or more ttys. A context is filled via one of the
* screen_redraw_start* variants which sets up (removes
* cursor etc) and figures out which tty_write_* function
* to use to write to the terminals, then the other
* screen_redraw_* functions are used to draw the screen,
* and screen_redraw_stop used to reset the cursor and
* clean up. These are used when changing window and a
* few other bits (status line).
* screen-write.c: Functions for modifying (writing into) the screen and
* optionally simultaneously updating one or more ttys.
* These are used in much the same way as the redraw
* functions. These are used to update when parsing
* input from the window (input.c) and for the various
* other modes which maintain private screens.
*
* If you're thinking this all seems too complicated, that's because it is :-/.
