It looks like having the empty error capture |_| on the else branch of
the if statement causes the else branch to be ignored by the compiler.
This should be a compile error, as the condition of the if statement is
a bool, not an error union.
These new functions allow testing commits without messing up the
pending state of the output and needing to rollback. The new apply()
function also makes the code considerably more concise.
I have encountered a crash (failing assert) if a view specified a fixed
size less than this minimum, and according to ifreund this behavior was
planned to be removed, anyway.
Notably, we no longer call both wlr_output_test and wlr_output_commit
when applying an output config, which seems to fix or workaround an
occasional crash since updating to wlroots 0.15.0.
Currently the view destruction sequence is started as soon as a view
is unmapped. However, this is incorrect as a client may map the view
again instead of destroying it.
Instead, only start the view destruction sequence when the underlying
xdg toplevel or xwayland surface is destroyed.
If the current Cursor.maybeResetState() function is called while in
passthrough mode, it will send a pointer motion event. This is
unnecessary as we have already sent the same pointer motion event at
least once.
Also refactor the code slightly and improve naming.
A transaction may move the current target of a cursor action to a
non-visible tag, make it fullscreen, or otherwise change things such
that the current cursor state no longer makes sense.
To handle this, check if we should reset cursor state every time a
transaction is committed.
This code is complex and increases maintenance burden but doesn't
add any functionality, only eye-candy.
Futhermore, neither I nor any of the core contributors use it.
There may be a place in river for such eye-candy down the line, in which
case this code could be revived. Currently river is early enough in its
development that our focus should be on core functionality instead.
A client is free to change its mind and request a different
size/anchor/etc after recieving the initial configure but before
attaching and committing the first buffer. This means that we should
respond to such a situation with a new configure.
mako has been observed doing this in the wild for example.
Currently in handleUnmap() we call View.unmap() before removing
listeners. However View.unmap() may destroy the view before returning
if the transaction started doesn't have to wait on any configures.
To ensure that we don't try to remove listeners which have already been
free'd, do this before calling View.unmap().
The Layout struct holds a pointer to the Output which becomes invalid
when the Output is destroyed so we must ensure all the layouts of an
Output are destroyed first.
Replace the current layout mechanism based on passing args to a child
process and parsing it's stdout with a new wayland protocol. This much
more robust and allows for more featureful layout generators.

Recover more gracefully from being hotplugged down to 0 outputs and then
gaining a new one. Move all views to the new output and restore the
focused output tags of the last output to be removed.
