This allows the compositor to avoid having to setup and teardown a
SIGBUS signal handler whenever it needs to read from this surface, as it
knows we won’t be able to shrink the file and so doesn’t have to protect
against that.
Only enabled on Linux, since only Linux has memfd_create()
Not sure why this became necessary though?!

Always apply defaults when creating a screen (the C-side global state
default will not have the intended values without this), and provide a
way to override default values with a new optional parameter
When a key is pressed, text is generated from xkb and attached to the
global key_event variable.
If another key is pressed before ibus replies, this text in global
variable would be overwritten before the processed reply comes in and
the wrong character would be input, as shown in logs with

Since the whole event is memcpy'd we can just use the text from the
event attached to the reply instead.
