We now emit button 6/7 events (when the client application grabs the
mouse). This buttons map to mouse wheel horizontal scroll events. Or, left/right
tilting, if you like.
Wayland report these as ‘axis’ events (just like regular scroll wheel events),
and thus we need to translate those scroll events to button events.
libinput does not define any mouse buttons for wheel tilts, so we add our own
defitions. These are added last in the BTN_* range, just before the BTN_JOYSTICK
events.
GNOME doesn’t send pointer enter after finishing a window move.
In subsequent move operations, it is also possible to make it skip sending
pointer leave when starting the move operations.
This caused foot to assert in debug builds, and add the same button multiple
times to the list of buttons currently being pressed.
ncurses has had a bug where mouse support is completely disabled if the terminfo
didn’t have kmous=\E[M, *or*, the terminfo *name* contained ‘xterm’.
This appears to have been fixed.
Thus, change kmous to \E[<, and set xm/XM accordingly. With this, ncurses
application will use the SGR mouse reporting mode, instead of the legacy
reporting mode.

We’re using floating point math, as a way to ensure that sextant primitives
overlap, rather than leaving empty spaces, or being uneven, when the cell
width/height isn’t divisible with 2 (width) or 3 (height).
This gets rid of all floating point math from the sextant drawing functions.
That is, encode which “pieces” make up each quad in a static array, and use a
single function to draw all quads using the four primitives “upper left/right,
lower left/right”.
We render the inverted wedges by first rendering a non-inverted triangle, and
then inverting it with PIXMAN_OP_OUT.
In cases where truncating and round():ing the triangle points have different
results, the final, inverted wedge ends up being unaligned with the
corresponding sixel(s).
This patch fixes that by handling the pre-inverted triangles
specifically. I.e. we don’t re-use the same triangle coordinates as the
corresponding non-inverted triangle.
When the foot window is closed, and we need to terminate the client application,
do this in an asynchronous fashion:
* Don’t do a blocking call to waitpid(), instead, rely on the reaper callback
* Use a timer FD to implement the timeout before sending SIGKILL (instead of
using SIGALRM).
* Send SIGTERM immediately (we used to *just* close the PTY, and then wait 2
seconds before sending SIGTERM).
* Raise the timeout from 2 seconds to 60
Full shutdown now depends on *two* asynchronous tasks - unmapping the window,
and waiting for the client application to terminate.
Only when *both* of these have completed do we proceed and call term_destroy(),
and the user provided shutdown callback.
