Expand description
output scaling properties
This event contains scaling geometry information
that is not in the geometry event. It may be sent after
binding the output object or if the output scale changes
later. If it is not sent, the client should assume a
scale of 1.
A scale larger than 1 means that the compositor will
automatically scale surface buffers by this amount
when rendering. This is used for very high resolution
displays where applications rendering at the native
resolution would be too small to be legible.
It is intended that scaling aware clients track the
current output of a surface, and if it is on a scaled
output it should use wl_surface.set_buffer_scale with
the scale of the output. That way the compositor can
avoid scaling the surface, and the client can supply
a higher detail image.
The scale event will be followed by a done event.

Deserialize from the given buffer. Returns deserialized message, and
number of bytes and file descriptors consumed, respectively.
This method tests for self
and other
values to be equal, and is used
by ==
.
This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
Serialize into the buffered writer. This function returns no errors,
failures in seializing are generally program errors, and triggers
panicking.
