protocol: remove scaler.xml

Browse Source 
The stable version of the scaling and cropping extension is found in
wayland-protocols as viewporter.xml.

Remove scaler.xml as nothing uses it.

The global interface exposing surface cropping and scaling

<description summary="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 allows to define the source rectangle (src_x,
src_y, src_width, src_height) from where to take the wl_buffer
contents, and scale that to destination size (dst_width,
dst_height). This state is double-buffered, and is applied on the
next 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 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, the surface size becomes the source
rectangle size rounded up to the nearest integer. If the source size
is already exactly integers, this results in cropping without scaling.
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 (wl_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 the source rectangle is partially or completely outside of the
wl_buffer, then the surface contents are undefined (not void), and
the surface size is still dst_width, dst_height.
The x, y arguments of wl_surface.attach are applied as normal to
the surface. They indicate how many pixels to remove from the
surface size from the left and the top. In other words, they are
still in the surface-local coordinate system, just like dst_width
and dst_height are.
If the wl_surface associated with the wl_viewport is destroyed,
the wl_viewport object becomes inert.
If the wl_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.
