Add anew config option, ‘bell=none|set-urgency’. When set to
‘set-urgency’, the margins will be painted in red (if the window did
not have keyboard focus).
This is intended as a cheap replacement for the ‘urgency’ hint, that
doesn’t (yet) exist on Wayland.

E.g. only set mouse reporting to NONE, if mouse reporting mode is SGR
and an DECRST SGR is issued.
Do *not* reset the mouse mode if e.g. mouse reporting mode is SGR and
an DECRST URXVT is issued.
Previously, our secondary DA response indicated a) VT420, b) an XTerm
version number.
Now, we indicate VT220 (which corresponds to the primary DA response),
and we report foot's version number as MMmmpp. I.e major, minor and
patch versions, using two digits.
E.g. 1.4.2 is encoded as 010402
A lot of the escape sequences on the "CSI Ps ; Ps ; Ps t" form are
expected to return a reply. Thus, not having these implemented means
we will hang if the client sends these escapes.
Not all of these escapes can be meaningfully implemented on Wayland,
and thus this implementation is best effort.
We now support the following escapes:
* 11t - report if window is iconified (always replies "no")
* 13t - report window position (always replies 0,0)
* 13;2t - report text area position (replies with margins, since we
cannot get the window's position)
* 14t - report text area size, in pixels
* 14;2t - report window size, in pixels
* 15t - report screen size, in pixels
* 16t - report cell size, in pixels
* 18t - report text area size, in cells
* 19t - report screen size, in cells
All are printf() formatter related. Even if a variable is e.g. a
'short', when used in an expression like '<variable> - 1' it is
promoted to an 'int'.
Closes#16
This fixes an issue where we failed to restore the cursor correctly
when exiting from the alternate screen, if the client had sent escapes
to save the cursor position while inside the alternate screen.
This was because we used the *same* storage for saving the cursor
position through escapes, as for saving it when entering the alternate
screen.
Fix by using a custom variable dedicated to normal <--> alt screen
switching.
Update the sixels' 'row' attribute when re-flowing a grid, to ensure
it is rendered at the correct place.
This should work in most cases, but will break when the cell size has
changed (e.g. font size increase/decrease, or a DPI change).
This patch also moves the sixel image list from the terminal struct
into the grid struct. The sixels are per-grid after all.
Assume we don't handle 'CSI 4 X'. Furthermore, assume we receive the
following: 'CSI 1;2;3;4X'. In this case, only log '4X' as un-handled,
not the entire CSI string.
This implements the following queries:
* report window size in pixels
* report cell size in pixels
* report window size in chars
We also log a warning for the remaining window operation queries.
