fix the position of the cursor image after turning all the monitors on

remove unused #include

do not check if `session` is non-NULL

wlr_session_change_vt() is a no-op if session == NULL

do not explicitly destroy some wlroots interfaces

they are destroyed when the wayland display is destroyed

enable debug symbols by default

they does not affect performance and the size's increase is negligible

fix docs

copied from tinywl

fix destroynotify() docs

check toplevel resource instead of client's xdg_shell to set bounds

use the new wlroots function to get a toplevel from a wlr_surface

References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4419

explicitly return -1 in the first check in toplevel_from_wlr_surface

do not use #ifdef -> #else -> #endif in client_is_x11

all other funcions use #ifdef -> #endif

delete unused functions

style fixes in client_is_float_type

correctly check if the scene node is enabled in client_is_rendered_on_mon

do not use magical numbers to check edges

the interface is declared stable, which means we could just use 0 anyway

simplify client_get_clip

the clips for xwayland and xdg clients are pretty similar, after all we only
need to adjust x and y for xdg clients

prevent a use-after-free at exit

do not compute layout box twice

make sure fullscreen clients have the right size

fix screen artifacts when setting gamma

the artifacts were caused because we tried to set the gamma right after
receiving the event, this resulted in two pending page-flips, which
not always play well together.

This also seems to fix a screen freeze when turning on a monitor that has
gamma.

Additionally the current method won't work once [0] is merged
