<description summary="communicate corner radius of layer surfaces">
This protocol provides a way for clients to communicate the
corner radius of their layer shell surfaces, should they use rounded corners.
This hint can then be used by the compositor to draw fitting blur outlines
or prevent overdrawing of other server-side drawn interfaces.
</description>
<interface name="layer_corner_radius_manager_v1" version="1">
<description summary="corner radius manager for layer surfaces">
Manager for creating corner-radius objects for surfaces.
This is designed for layer shell surfaces but works with any wl_surface.
</description>
<request name="destroy" type="destructor">
<description summary="Destroy the global">
Informs the server that the client will no longer use this global.
Any previously created corner-radius objects remain valid until destroyed.

<description summary="Create a new corner-radius object for a surface">
Instantiate an interface extension for the given wl_surface to specify corner radius.
If the given wl_surface already has a layer_corner_radius_surface_v1 object associated,
the corner_radius_exists protocol error will be raised.

<description summary="corner radius for a surface">
The corner-radius object provides a way to specify a corner-radius
for its associated surface.
If the wl_surface associated with the layer_corner_radius_surface_v1
object has been destroyed, this object becomes inert. Any further requests
other than destroy will raise the surface_destroyed protocol error.

<request name="destroy" type="destructor">
<description summary="Destroy the corner-radius object">
Informs the server that the client will no longer be using this protocol
object. The corner radius will be unset on the next commit.

</request>
<request name="set_radius">
<description summary="Set corner radius">
This request sets the hinted corner radius values for the surface.
The corner radius hint is double-buffered state and will be applied on
the next wl_surface.commit.
The value is given in logical space relative to the surface geometry.

Unsets any previously hinted corner radius values without invalidating the object for later use.
Can be used by clients that possibly have temporary irregular shapes.
