Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

data-device: Implement DnD actions The policy in weston in order to determine the chosen DnD action is deliberately simple, and is probably the minimals that any compositor should be doing here. Besides honoring the set_actions requests on both wl_data_source and wl_data_offer, weston now will emit the newly added "action" events notifying both source and dest of the chosen action. The "dnd" client has been updated too (although minimally), so it notifies the compositor of a "move" action on both sides. Changes since v8: - Add back wl_data_offer.source_actions emission, gone during last code shuffling. Fix nits found in review. Changes since v7: - Fixes spotted during review. Add client-side version checks. Implement .action emission as specified in protocol patch v11. Changes since v6: - Emit errors as defined in DnD actions patch v10. Changes since v5: - Use enum types and values for not-a-bitfield stored values. handle errors when finding unexpected dnd_actions values. Changes since v4: - Added compositor-side version checks. Spaces vs tabs fixes. Fixed resource versioning. Initialized new weston_data_source/offer fields. Changes since v3: - Put data_source.action to use in the dnd client, now updates the dnd surface like data_source.target events do. Changes since v2: - Split from DnD progress notification changes. Changes since v1: - Updated to v2 of DnD actions protocol changes, implement wl_data_offer.source_actions. - Fixed coding style issues.

data-device: Implement DnD actions The policy in weston in order to determine the chosen DnD action is deliberately simple, and is probably the minimals that any compositor should be doing here. Besides honoring the set_actions requests on both wl_data_source and wl_data_offer, weston now will emit the newly added "action" events notifying both source and dest of the chosen action. The "dnd" client has been updated too (although minimally), so it notifies the compositor of a "move" action on both sides. Changes since v8: - Add back wl_data_offer.source_actions emission, gone during last code shuffling. Fix nits found in review. Changes since v7: - Fixes spotted during review. Add client-side version checks. Implement .action emission as specified in protocol patch v11. Changes since v6: - Emit errors as defined in DnD actions patch v10. Changes since v5: - Use enum types and values for not-a-bitfield stored values. handle errors when finding unexpected dnd_actions values. Changes since v4: - Added compositor-side version checks. Spaces vs tabs fixes. Fixed resource versioning. Initialized new weston_data_source/offer fields. Changes since v3: - Put data_source.action to use in the dnd client, now updates the dnd surface like data_source.target events do. Changes since v2: - Split from DnD progress notification changes.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Besides honoring the set_actions requests on both wl_data_source and wl_data_offer, weston now will emit the newly added "action" events notifying both source and dest of the chosen action. The "dnd" client has been updated too (although minimally), so it notifies the compositor of a "move" action on both sides. Changes since v8: - Add back wl_data_offer.source_actions emission, gone during last code shuffling. Fix nits found in review. Changes since v7: - Fixes spotted during review. Add client-side version checks. Implement .action emission as specified in protocol patch v11. Changes since v6: - Emit errors as defined in DnD actions patch v10. Changes since v5: - Use enum types and values for not-a-bitfield stored values. handle errors when finding unexpected dnd_actions values. Changes since v4: - Added compositor-side version checks. Spaces vs tabs fixes. Fixed resource versioning. Initialized new weston_data_source/offer fields. Changes since v3: - Put data_source.action to use in the dnd client, now updates the dnd surface like data_source.target events do. Changes since v2: - Split from DnD progress notification changes.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>
