Get snapping to character grid working again, avoid crashes when attempting
to resize below 1x1 character cell, only redraw when size actually changes.
Also, rename window_get_child_rectangle() to window_get_child_allocation().
Implement the concealed attribute, and 16-colour attributes. Fix a bug in
256-colour attributes that prevented them from working in elinks.

Fix several bugs in the previous patches. Fix inverse inverse video
with bold attribute, incorrect duplication of attributes when scrolling
up, underline aliasing, bottom scroll margin adjustment when resizing,
and unnecessary sleep when sending terminal reports. Change TERM
environment variable to xterm-256color to better reflect terminal
capabilities (although it still doesn't emulate all of xterm).

Includes the 3 vt100 character sets. Some of the graphic symbols don't
display because they are not included in the default font. Apparantly
the cairo toy font API doesn't do font substitution.

Upgrade and refactor terminal_data to properly handle non-csi escape
codes, control characters in escape codes, and invalid escape sequences.
Also fix a buffer overflow in the escape sequence buffer.

Use TIOCSWINSZ ioctl to set window size on terminal resize.
This causes applications to be notified of the resize event.

Includes bold, underline, inverse, and blink attributes. Blink is
rendered bold as in xterm. Supports xterm's 256 color palette.

The new map_toplevel() request no longer specifies a position and takes
the size from the attached buffer. The attach request now takes a
position relative to the top-left corner of the old buffer to let
clients specify the relative position of the new buffer.
This is an example of how to animate window resizing. The size is
animated by a simple physics model that allows the user to cancel the
animation halfway and still look good.
