Apparently on FreeBSD one cannot unlink shared mem if it is not created
with write permissions.
Adding IWRITE to the permissions when creating the shared memory is
harmless. It means any process running as the user can either write to
the file or delete it. Deleting was already possible except on FreeBSD.
As for writing, it's needed on FreeBSD for shared memory to be useable
at all, and since processes running as the user can already completely
access all their data, kitty config files, tty pipes, etc. allowing them
to write to the SHM used here doesnt grant any significant new
capability, since they could just write to ssh.conf in the kitty config
folder to get the ssh kitten to do whatever they like.

It's easier to type, and cuter.
Also, most, if not all of the TUI parts of
kitty's kittens will eventually be re-written into kitten.
The only downside I can see is that we cant tab complete kitty
anymore, but hopefully there will be less reason to run kitty
from the shell as command line tools migrate to kitten.
Meowrrrr!!!
Only call wl_surface_commit() after a resize when the correct size buffer is
attached to the surface. This is ensured by setting a flag on the window that prevents
all surface commits till it is cleared. The flag is cleared at next
eglSwapBuffers().
I dont actually understand if this guarantees that the
buffer size is always correct. For example, if the back buffer is
latched when wl_egl_resize_window() is called, the backbuffer will be
correct only after two swaps (I think). Or maybe the old back buffer is
discarded, I cant find any documentation about it.
All I can say is that doing it this way seems to fix the issue.
Thanks to @jadahl for his help with tracking down the root cause.

The problem was that on Wayland if the buffer contains pixels with alpha
< 1 they are blended with something, even if the window is opaque. Under
mutter that something was the previous frame, under sway it was the
background/whatever is under the window.
So when blending the tint color, use a blend mode that results in opaque
pixels.

Dunno why kwin uses drag and drop callbacks when pasting into Firefox on
Wayland, but then this is Wayland, so every stupid thing imaginable will
be done at least once.
