This fixes :
- leaking the mask used to simulate transparency ;
- code style (definitions moved up, use of brackets) ;
- applying an opaque region when transparency is
wanted (shound not happen).

If the client attaches a new SHM buffer with a different format from a
previous one then we ought to trigger a full upload so that GL can
allocate a new texture. Otherwise Weston would technically be doing
invalid operations because it would call glTexSubImage2D with a
different format from the one specified in glTexImage2D. Presumably it
would also mean GL would have to convert the buffer as it copies the
sub-region in which isn't ideal.
This patch makes it decide the GL format when the buffer is attached
instead of when processing the damage and it will set
needs_full_upload if it is different from what it used before.
When the alpha channel of a surface is changed and the surface
refreshed, pixman renderer will now apply a mask corresponding
to the alpha channel value.
This allows visual effects like shell fade in, shell fade out,
window switching, to work when using pixman renderer.

Previously when uploading SHM data we would initialise the texture
with glTexImage2D and NULL data when the buffer is attached. Then if
the GL_EXT_unpack_subimage extension is available we would always use
glTexSubImage2D to upload the data. The problem with that is that the
first glTexImage2D was always setting the internal format to
GL_BGRA_EXT and then if a 16-bit texture is used we would later call
glTexSubImage2D with a data format of GL_RGBA. Under GLES2 the
internal format must always match the data format so this is
technically invalid.
This patch makes it so that it always calls glTexImage2D when flushing
the damage for the first time. That way it will use the right internal
format and we don't need to call glTexImage2D with NULL data.

Ensure, that the resulting surface size is at least 1x1, even when
destination size is not set and source size is zero. Previously this
lead to zero surface size.
This can still happen due to wl_viewport.set(#, #, 0, 0, #, #) followed
by wl_viewport.set_destination(-1, -1).

Let's make the source and destination size rules consistent: neither can
have zero, {-1, -1} disables it, and other negatives are not allowed.
The sanity of allowing zero sized source rectangle as debatable. Now the
minimum becomes 1/256x1/256, and with output_scale the actual samples
may be even smaller. That should be enough.
On not allowed values, raise a protocol error. This should help catch
bugs in clients that accidentally send garbage values.
The old wl_viewport.set request remains the same, and can still produce
zero sized source rectangle.

This adds a plugin called screen-share.so. If the screen-share.so module
is imported, it will add the CTRL+ALT+s keybinding to start a screen
sharing session. If you press CTRL+ALT+S, weston will spawn another copy
of weston, this time with the RDP backend, and mirrors the current screen
to it and adds any seats from RDP as aditional seats. The current screen
is defined as the one with the mouse pointer. Currently the CTRL+ALT+s
keybinding is hardcoded as the only way to activate screen sharing. If, at
some point, shells want more control over the screen sharing process, the
API's should be easy to update and export to make this possible.
For security, the command and path to weston is currently hard-coded. It
would not take much aditional code to make this configurable or to allow a
shell to launch other screen-sharing programs. However, handling those
security issues is outside the scope of this patch so it is hard-coded for
now.

This patch adds an option to the RDP compositor to disable
desktop resizes initiated by RDP peer. The current behaviour
is that if an incoming RDP peer suggests a resolution that is
not the current one, a mode_switch() is done and the desktop is
resized to that new resolution. This new flag allows to disable
that behaviour. If the flag is set, the new behaviour is that the
RDP peer will be instructed to resize to the size of the desktop.

On startup weston now detects the WAYLAND_SERVER_SOCKET environment
variable. If found, weston does not create the display like normal, but
instead directly adds a client corresponding to the given fd. This,
combined with the fullscreen shell, allows a process to spawn weston and
use it as a backend.

The CURSOR_PLANE capability indicates that the backend has a concept of a
cursor plane and can handle a cursor without compositing. This is currently
only advertised by the DRM backend.
The ARBITRARY_MODE flag specifies that the backend is capable of switching to
virtually any resolution. This is currently only advertised in the RDP
backend. While it's a bit buggy right now, it should be capable of this.

This patch removes the extra modes parameter for the RDP compositor. And
make it support any mode that is requested (be aware that RDP client may not
support all possible modes, especially odd resolution).
This new version fixes remarks done by Jason Ekstrand. It also fixes
some missing spaces between if and (.
Bump wl_scaler and wl_viewport versions to 2. Add new requests
wl_viewport.set_source and .set_destination, which are meant to replace
wl_viewport.set request.
Now a client can set and unset just one of source rectangle and
destination size. Define the semantics when one of these is unset.
Implement these semantics changes in compositor and pixman renderer.

Remove the explicit boolean variable, and use illegal width to denote
"not set".
Split the boolean into two, so we can later start having buffer.src_*
and surface.* set or not set independently. This may become useful when
the wl_viewport interface is changed to allow modifying them separately.
At the moment, both buffer.src_width and surface.width conditions are
always in sync.

There is no need for weston_subsurface_commit_to_cache() to leave the
pending.buffer set. Reset it to NULL.
This makes pending.buffer always NULL if pending.newly_attached == 0.
IOW, pending.buffer cannot be non-NULL unless
pending.newly_attached == 1.
Therefore no need to check pending.buffer nor cached.buffer_ref.buffer
for the weston_surface_attach() calls.

The gbm-format configuration option can now be specified per-output as
well as in the core config section. If it is not specified it will
default to the format specified in the core section. The
EGL_MESA_configless_context extension is required for this to work. If
this extension is available it will create a context without an
EGLConfig and then it will potentially use a different EGLConfig for
each output.
The gl-renderer interface has been changed so that it takes the EGL
attributes and visual ID in the create_output function as well as in
the create function.
Part of the gl_renderer_setup function only deals with checking EGL
extensions and doesn't need to have a current context. This patch
moves these checks so that they are done during gl_renderer_create
instead of waiting until we have an output. We will need this in a
later patch because some of the EGL extensions will affect how we
create the EGLSurface.
Commit fa1b3055 introducted a regression in the pixman renderer. In
particular, it would not draw properly with any output transform other
than normal, 180, 180-flipped, or 270-flipped. This patch fixes this
regression. The weston-scalar program appears to work normally at all
rotations with this patch. Therefore, this patch should fix the regression
while maintaining the added functionality from fa1b3055.

The client needs to know that the pointer is at a different position in
its surface. We can't send motion as that corresponds to the pointer
actually moving. Leaving the surface and entering at the new position
is a better semantic match and doesn't correspond to pointer motion
or user input.

This was always a little iffy. At least it could have been a signal,
but we now have focus signal, so lets just use that. We lose
the ability to detect unresponsive clients at key event time, but we
could add that back by adding a key_signal.
