Chromium surface augmenter

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, augmenter objects included.

Instantiate a buffer of the given size for the purpose of a solid color quad of a given color.

This buffer does not require resources in the compositor, so it is immediately reusable and shareable. So it is not responsible for sending wl_buffer.release or zwp_linux_buffer_release_v1.*_release events.

Instantiate an interface extension for the given wl_surface to extend composition of its content. If the given wl_surface already has a augmentation object associated, the delegate_exists protocol error is raised.

If needs to be called, this must be called before a surface role object is created.

Instantiate an interface extension for the given wl_subsurface to extend composition of its content. If the given wl_subsurface already has a augmentation object associated, the delegate_exists protocol error is raised.

Client will no longer be able to control the delegated composition properties of this surface. This does not change the existing delegated composition behavior.

[Deprecated]. Use set_rounded_corners_clip_bounds request below.

Informs the server that it must apply the rounded corners mask filter that shall be applied on next commit. Use set_rounded_corners_bounds instead.

Sets the surface destination viewport size, with subpixel accuracy. This state is double-buffered, and is applied on the next wl_surface.commit.

[Deprecated]. Use set_rounded_corners_clip_bounds request below.

Informs the server that it must apply the rounded clipping mask filter that shall be applied on next commit. The mask can be uniform for several surfaces and applied uniformally so that two or more surfaces visually look as a single surface with rounded corners. Please note this is can only be used on surfaces that are used as overlays, which must not have any subtrees. The rounding will be ignored if the bounds are outside of the surface.

Sets a background color of a this surface. This information will be associated with the next buffer commit. Please note this is different from solid color buffers, which creates a new buffer instance, and rather provides additional information how the buffer should be composited. Passing empty array means the background color is reset. The default value is determined by the Wayland compositor then.

[Deprecated] When set, this surface trusts all damage reported to this surface and descendant sub-surfaces is accurate, and will not try to recompute it. If not set, various changes like adding or removing a sub-surface, changing its position or stacking order, can cause full damage on this surface.

The initial state is disabled.

Informs the server that it must apply the rounded clipping mask filter that shall be applied on next commit. The mask can be uniform for several surfaces and applied uniformally so that two or more surfaces visually look as a single surface with rounded corners.

Since version 9, the bounds will be placed with its origin (top left corner pixel) at the location x, y of the surface local coordinate system. On version 8 or before, it is placed with its root surface coordinates, but this is deperecated.

Please note this is can only be used on surfaces that are used as overlays, which must not have any subtrees. The rounding will be ignored if the bounds are outside of the surface.

This schedules a clip rect to be applied when drawing this sub-surface. The clip will be placed with its origin (top left corner pixel) at the location x, y of the surface local coordinate system. The coordinates are not restricted to the surface area. Negative x and y values are allowed.

If all of x, y, width and height are -1.0, the clip rect is unset instead.

Initially, surfaces have no clip set. This state is double-buffered, and is applied on the next wl_surface.commit.

This sets a trace ID to connect the frame submission trace event flow at the client and the server side. This state is double-buffered, and is applied on the next wl_surface.commit.

The associated wl_surface's augmenter is removed. The change is applied on the next wl_surface.commit.

This schedules a sub-surface position change. The sub-surface will be moved so that its origin (top left corner pixel) will be at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative values are allowed.

The scheduled coordinates will take effect whenever the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details.

If more than one set_position request is invoked by the client before the commit of the parent surface, the position of a new request always replaces the scheduled position from any previous request.

The initial position is 0, 0. This state is double-buffered, and is applied on the next wl_surface.commit.

[Deprecated] Use set_clip_rect on augmented_surface instead. This schedules a clip rect to be applied when drawing this sub-surface. The clip will be placed with its origin (top left corner pixel) at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative x and y values are allowed.

If all of x, y, width and height are -1.0, the clip rect is unset instead.

Initially, surfaces have no clip set. This state is double-buffered, and is applied on the next wl_surface.commit.

This schedules a transform to be applied when drawing this sub-surface. This transform does not apply to any child surfaces of this sub-surface.

The matrix should be passed as an array of 6 floats in column major order. An empty array can be sent to set the transform to the identity matrix.

The initial transform is identity. This state is double-buffered, and is applied on the next wl_surface.commit.
