When a new client is spawned, fullscreen isn't disabled for all clients
in that monitor any more.
Instead, all fullscreen clients are kept fullscreen, while other clients
spawn in the background.
When fullscreen is disabled, all clients are rearranged.
This is made to make dwl more flexible allowing multiple fullscreen
clients at the same time, have floating clients on top of a fullscreen
one and let stuff happen without quitting fullscreen, like many other
WMs and DEs.
Disable fullscreen on all visible clients in that monitor also before
enabling it on another client.
quitallfullscreen() is reintroduced becouse is now more useful
set c->isfullscreen later to avoid making quitallfullscreen() disable
fullscreen on the current client
...in internal calls to restore pointer focus. Necessary for the
unclutter patch, and there's no harm in avoiding this call even in
mainline; might prevents issues in same edge cases.
Don't let internal calls to motionnotify(0) meant to update the pointer
focus from maplayersurfacenotify and destroylayersurfacenotify also
shift the keyboard focus to the surface under the cursor with
sloppyfocus.
wtf is the point of this crap? It makes the code harder to follow,
increases the line count and made me fail compilation a million times.
We shouldn't blindy follow everything about suckless's style.
Scaling a wlr_box without rounding can sometimes make the borders not
connected and nice. I noticed this when setting scale in monrules to 1.2
So I've went and copied what Sway did in desktop/output.c but without
having a second function and now using a random rounding macro I found
on the internet so as to not use round from math.h.
Distribute it as a patch like in dwm since graphical applications
usually provide their own keybinding; I guess it's only for terminals.
Note that even though these commits don't let you open multiple windows
in fullscreen and cycle between them like in dwm, with just
fullscreennotify spawning new windows or changing tag would still exit
fullscreen automatically, but you would have to toggle fullscreen twice
when switching back to the fullscreen window to enter fullscreen again,
so this is better since it avoids that.
quitfullscreen() was replicating the functionalities of setfullscreen(c,
0)
Reusing setfullscreen() in quitfullscreen() leads to a 3 line function,
which is useless since quitfullscreen() is used once anyway
This fixes the bug that happens when changing workspace (or any time
arrange() is called) where there are fullscreen windows, which are still
fullscreen but leave the space for layer surfaces like waybar (which
should be hidden when going fullscreen)
Also as soon one fullscreen window is found hte function returns to
improve efficiency
Store position and size of windows before going fullscreen. This is more
efficient than arrange() and also works with floating windows
All the clients keep their original position because arrange() isn't
used after quitting fullscreen
