#[doc = "an onscreen surface\n\nA surface is a rectangular area that is displayed on the screen.\nIt has a location, size and pixel contents.\n\nThe size of a surface (and relative positions on it) is described\nin surface-local coordinates, which may differ from the buffer\ncoordinates of the pixel content, in case a buffer_transform\nor a buffer_scale is used.\n\nA surface without a \"role\" is fairly useless: a compositor does\nnot know where, when or how to present it. The role is the\npurpose of a wl_surface. Examples of roles are a cursor for a\npointer (as set by wl_pointer.set_cursor), a drag icon\n(wl_data_device.start_drag), a sub-surface\n(wl_subcompositor.get_subsurface), and a window as defined by a\nshell protocol (e.g. wl_shell.get_shell_surface).\n\nA surface can have only one role at a time. Initially a\nwl_surface does not have a role. Once a wl_surface is given a\nrole, it is set permanently for the whole lifetime of the\nwl_surface object. Giving the current role again is allowed,\nunless explicitly forbidden by the relevant interface\nspecification.\n\nSurface roles are given by requests in other interfaces such as\nwl_pointer.set_cursor. The request should explicitly mention\nthat this request gives a role to a wl_surface. Often, this\nrequest also creates a new protocol object that represents the\nrole and adds additional functionality to wl_surface. When a\nclient wants to destroy a wl_surface, they must destroy this 'role\nobject' before the wl_surface.\n\nDestroying the role object does not remove the role from the\nwl_surface, but it may stop the wl_surface from \"playing the role\".\nFor instance, if a wl_subsurface object is destroyed, the wl_surface\nit was created for will be unmapped and forget its position and\nz-order. It is allowed to create a wl_subsurface for the same\nwl_surface again, but it is not allowed to use the wl_surface as\na cursor (cursor is a different role than sub-surface, and role\nswitching is not allowed)."]

#[doc = "sub-surface interface to a wl_surface\n\nAn additional interface to a wl_surface object, which has been\nmade a sub-surface. A sub-surface has one parent surface. A\nsub-surface's size and position are not limited to that of the parent.\nParticularly, a sub-surface is not automatically clipped to its\nparent's area.\n\nA sub-surface becomes mapped, when a non-NULL wl_buffer is applied\nand the parent surface is mapped. The order of which one happens\nfirst is irrelevant. A sub-surface is hidden if the parent becomes\nhidden, or if a NULL wl_buffer is applied. These rules apply\nrecursively through the tree of surfaces.\n\nThe behaviour of a wl_surface.commit request on a sub-surface\ndepends on the sub-surface's mode. The possible modes are\nsynchronized and desynchronized, see methods\nwl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized\nmode caches the wl_surface state to be applied when the parent's\nstate gets applied, and desynchronized mode applies the pending\nwl_surface state directly. A sub-surface is initially in the\nsynchronized mode.\n\nSub-surfaces have also other kind of state, which is managed by\nwl_subsurface requests, as opposed to wl_surface requests. This\nstate includes the sub-surface position relative to the parent\nsurface (wl_subsurface.set_position), and the stacking order of\nthe parent and its sub-surfaces (wl_subsurface.place_above and\n.place_below). This state is applied when the parent surface's\nwl_surface state is applied, regardless of the sub-surface's mode.\nAs the exception, set_sync and set_desync are effective immediately.\n\nThe main surface can be thought to be always in desynchronized mode,\nsince it does not have a parent in the sub-surfaces sense.\n\nEven if a sub-surface is in desynchronized mode, it will behave as\nin synchronized mode, if its parent surface behaves as in\nsynchronized mode. This rule is applied recursively throughout the\ntree of surfaces. This means, that one can set a sub-surface into\nsynchronized mode, and then assume that all its child and grand-child\nsub-surfaces are synchronized, too, without explicitly setting them.\n\nIf the wl_surface associated with the wl_subsurface is destroyed, the\nwl_subsurface object becomes inert. Note, that destroying either object\ntakes effect immediately. If you need to synchronize the removal\nof a sub-surface to the parent surface update, unmap the sub-surface\nfirst by attaching a NULL wl_buffer, update parent, and then destroy\nthe sub-surface.\n\nIf the parent wl_surface object is destroyed, the sub-surface is\nunmapped."]
