Ben Boeckel 7bb84266b8 Fix drawing to incorporate translation
Not sure of the performance hits here. Also seems as though output_width
and char_width are not strictly necessary anymore since we calculate
them as we go along.

Also changed is that when a wide character gets split by a translate or
a region cutoff, the extra space is replaced with '…'. This is necessary
at least on the left to avoid jumps when the character appears when
scrolling. Not sure if this behavior is also wanted on the right. Is
there a "partial character" codepoint for when there isn't enough space
to display a full character?

vty is a terminal interface library.

Vty currently provides:

* Automatic handling of window resizes.

* Supports Unicode characters on output, automatically setting and
  resetting UTF-8 mode for xterm. Other terminals are assumed to support 

* Efficient output. 

* Minimizes repaint area, thus virtually eliminating the flicker
  problem that plagues ncurses programs.

* A pure, compositional interface for efficiently constructing display
  images.

* Automatically decodes keyboard keys into (key,[modifier]) tuples.

* Automatically supports refresh on Ctrl-L.

* Automatically supports timeout after 50ms for lone ESC (a barely
  noticable delay)

* Interface is designed for relatively easy compatible extension.

* Supports all ANSI SGR-modes (defined in console_codes(4)) with
  a type-safe interface. 

* Properly handles cleanup.

Current disadvantages:

* The character encoding of the output terminal is assumed to be UTF-8.

* Minimal support for special keys on terminals other than the
  linux-console.  (F1-5 and arrow keys should work, but anything
  shifted isn't likely to.)

* Uses the TIOCGWINSZ ioctl to find the current window size, which
  appears to be limited to Linux and *BSD.
