// WpViewport : crop and scale interface to a wl_surface
//
// An additional interface to a wl_surface object, which allows the
// client to specify the cropping and scaling of the surface
// contents.
//
// This interface works with two concepts: the source rectangle (src_x,
// src_y, src_width, src_height), and the destination size (dst_width,
// dst_height). The contents of the source rectangle are scaled to the
// destination size, and content outside the source rectangle is ignored.
// This state is double-buffered, see wl_surface.commit.
//
// The two parts of crop and scale state are independent: the source
// rectangle, and the destination size. Initially both are unset, that
// is, no scaling is applied. The whole of the current wl_buffer is
// used as the source, and the surface size is as defined in
// wl_surface.attach.
//
// If the destination size is set, it causes the surface size to become
// dst_width, dst_height. The source (rectangle) is scaled to exactly
// this size. This overrides whatever the attached wl_buffer size is,
// unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
// has no content and therefore no size. Otherwise, the size is always
// at least 1x1 in surface local coordinates.
//
// If the source rectangle is set, it defines what area of the wl_buffer is
// taken as the source. If the source rectangle is set and the destination
// size is not set, then src_width and src_height must be integers, and the
// surface size becomes the source rectangle size. This results in cropping
// without scaling. If src_width or src_height are not integers and
// destination size is not set, the bad_size protocol error is raised when
// the surface state is applied.
//
// The coordinate transformations from buffer pixel coordinates up to
// the surface-local coordinates happen in the following order:
// 1. buffer_transform (wl_surface.set_buffer_transform)
// 2. buffer_scale (wl_surface.set_buffer_scale)
// 3. crop and scale (wp_viewport.set*)
// This means, that the source rectangle coordinates of crop and scale
// are given in the coordinates after the buffer transform and scale,
// i.e. in the coordinates that would be the surface-local coordinates
// if the crop and scale was not applied.
//
// If src_x or src_y are negative, the bad_value protocol error is raised.
// Otherwise, if the source rectangle is partially or completely outside of
// the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
// when the surface state is applied. A NULL wl_buffer does not raise the
// out_of_buffer error.
//
// If the wl_surface associated with the wp_viewport is destroyed,
// all wp_viewport requests except 'destroy' raise the protocol error
// no_surface.
//
// If the wp_viewport object is destroyed, the crop and scale
// state is removed from the wl_surface. The change will be applied
// on the next wl_surface.commit.
