When we detect an error in yml_parser_parse(), we handle that
specifically, and then jump to the generic error handler.
The generic error handler overwrites the previously formatted error
before cleaning up and returning.
This meant that a) the actual error message was lost, and replaced
with a generic “unknown error”, and b) the dynamically allocated error
string buffer was leaked.
This is done by update_size(). Setting it in xdg_output_handle_done()
causes update_size() to do an early exit, and thus we end up never
actually configuring the surface.
We also never instantiate a pixman image, which led to a hard crash at
startup when the user had configured a specific output to use.
This allows the backend to support multi-seat "properly", by checking
against the correct seat. Before this, when we used a single, global
xcursor value, a seat whose pointer needed to be updated would not be
updated.
Instead, roundtrip once all globals have been handled. This means all
listeners have been registered.
When we detect a specific monitor to map to, and it has a non-default
scale, update the cursor theme (since it depends on the scale).
We only care about the mouse. We now track per-seat cursor positions
and cursor themes.
Any enter/leave/motion/button event will call the bar on_mouse()
method using the coordinates from the "current" seat.
Since the bar framework doesn't deal with multi-seats at all, we
internally, in the backend, track the currently active seat. This is
the seat which we last saw any kind of events from.
This is used in e.g. set_cursor(), which is called from the bar.
Time remaining is now taken from 'time_to_empty_now' if available. If
not, use 'energy' + 'power' if available, and if those does not exist,
use 'charge' + 'current'.
If neither exists, hardcode to 99:00.
This means you can now do either
ignore: [/dev/sda]
to ignore all partitions on /dev/sda, or
ignore: [/dev/sda1]
to ignore only the first partition on /dev/sda.
