<description summary="experimental color management protocol">
The aim of this color management extension is to get HDR games working quickly,
and have an easy way to test implementations in the wild before the upstream
protocol is ready to be merged.
For that purpose it's intentionally limited and cut down and does not serve
all uses cases.

<description summary="protocol to assign icons to toplevels">
This protocol allows clients to set icons for their toplevel surfaces
either via the XDG icon stock (using an icon name), or from pixel data.
A toplevel icon represents the individual toplevel (unlike the application

shown in window switchers, window overviews and taskbars that list
individual windows.
This document adheres to RFC 2119 when using words like "must",

<request name="set_icon">
<description summary="set an icon on a toplevel window">
This request assigns the icon 'icon' to 'toplevel', or clears the
toplevel icon if 'icon' was null.
This state is double-buffered and is applied on the next
wl_surface.commit of the toplevel.
After making this call, the xdg_toplevel_icon_v1 provided as 'icon'
can be destroyed by the client without 'toplevel' losing its icon.
The xdg_toplevel_icon_v1 is immutable from this point, and any
future attempts to change it must raise the
'xdg_toplevel_icon_v1.immutable' protocol error.
The compositor must set the toplevel icon from either the pixel data
the icon provides, or by loading a stock icon using the icon name.
See the description of 'xdg_toplevel_icon_v1' for details.
If 'icon' is set to null, the icon of the respective toplevel is reset
to its default icon (usually the icon of the application, derived from
its desktop-entry file, or a placeholder icon).
If this request is passed an icon with no pixel buffers or icon name
assigned, the icon must be reset just like if 'icon' was null.

<event name="icon_size">
<description summary="describes a supported &amp; preferred icon size">
This event indicates an icon size the compositor prefers to be
available if the client has scalable icons and can render to any size.
When the 'xdg_toplevel_icon_manager_v1' object is created, the
compositor may send one or more 'icon_size' events to describe the list
of preferred icon sizes. If the compositor has no size preference, it
may not send any 'icon_size' event, and it is up to the client to
decide a suitable icon size.
A sequence of 'icon_size' events must be finished with a 'done' event.
If the compositor has no size preferences, it must still send the
'done' event, without any preceding 'icon_size' events.

<interface name="xdg_toplevel_icon_v1" version="1">
<description summary="a toplevel window icon">
This interface defines a toplevel icon.
An icon can have a name, and multiple buffers.
In order to be applied, the icon must have either a name, or at least
one buffer assigned. Applying an empty icon (with no buffer or name) to
a toplevel should reset its icon to the default icon.
It is up to compositor policy whether to prefer using a buffer or loading
an icon via its name. See 'set_name' and 'add_buffer' for details.

</request>
<request name="set_name">
<description summary="set an icon name">
This request assigns an icon name to this icon.
Any previously set name is overridden.
The compositor must resolve 'icon_name' according to the lookup rules
described in the XDG icon theme specification[1] using the
environment's current icon theme.
If the compositor does not support icon names or cannot resolve
'icon_name' according to the XDG icon theme specification it must
fall back to using pixel buffer data instead.
If this request is made after the icon has been assigned to a toplevel
via 'set_icon', a 'immutable' error must be raised.

<request name="add_buffer">
<description summary="add icon data from a pixel buffer">
This request adds pixel data supplied as wl_buffer to the icon.
The client should add pixel data for all icon sizes and scales that
it can provide, or which are explicitly requested by the compositor
via 'icon_size' events on xdg_toplevel_icon_manager_v1.
The wl_buffer supplying pixel data as 'buffer' must be backed by wl_shm
and must be a square (width and height being equal).
If any of these buffer requirements are not fulfilled, a 'invalid_buffer'
error must be raised.
If this icon instance already has a buffer of the same size and scale
from a previous 'add_buffer' request, data from the last request
overrides the preexisting pixel data.
The wl_buffer must be kept alive for as long as the xdg_toplevel_icon
it is associated with is not destroyed, otherwise a 'no_buffer' error
is raised. The buffer contents must not be modified after it was
assigned to the icon.
If this request is made after the icon has been assigned to a toplevel
via 'set_icon', a 'immutable' error must be raised.
