Arnaud Vrac 49a8d9997b gl-renderer: fix pixel format used in texture uploads when using R/RG textures
In glTexImage2D / glTexSubImage2D calls, the only pixel formats allowed
for the GL_R8 and GL_RG internal formats are respectively GL_RED and
GL_RG [1].

Make sure we match this requirement, as some drivers will fail with the
current code.

Quentin Glidic 8e8fa8e885 libweston-desktop/xwayland: Make sure racy surfaces are properly mapped
This fixes a race between Xwayland committing the surface content via
the wl_surface, and the XWM setting the role of the surface.
We now keep track of the (first) content commit on the surface and
forward it to the shell when we finally get the role.
There is no need to track later changes, as the only way for Xwayland to
unmap a surface is to destroy it.

libweston-desktop: add signal for title/app-id changes
As discussed on
https://lists.freedesktop.org/archives/wayland-devel/2017-August/034720.html,
it's useful for the shell implementation to know when these change,
for example to relay the information on to taskbars or similar.

To avoid ABI changes or the need to make the weston_desktop_surface
definition public, new functions are introduced for attaching
listeners to these signals.

Derek Foreman e1af3d8d9d desktop-shell: Handle the fullscreen to maximized case safely
When a client transitions from maximized to fullscreen to maximized (run
weston-terminal, maximize it, hit f11 twice) we're sending size 0,0 for
the unfullscreen configure, which still has maximized set.

This results in clients correctly picking any size they like, and weston
disconnecting them for it.

Instead, pass the correct maximized size.

Daniel Stone b040974398 gl-renderer: Set pitch correctly for subsampled textures
zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
plane, but wl_shm only takes a single pitch parameter; the pitch for
secondary planes must be inferred.

Multi-plane sub-sampled textures have partial width/height, e.g.
YUV420/I420 has a full-size Y plane, followed by a half-width/height U
plane, and a half-width/height V plane.

GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the
pitch for secondary planes by the subsampling factor. gl-renderer was
not doing this, and instead just using the (larger) stride provided by
the client for all planes in the buffer.

Fix gl-renderer to divide pitch by the subsampling factor when uploading
from subsampled SHM buffers into GL textures, also dividing co-ordinates
when doing offset partial uploads.

Tested with:
  $ gst-launch-1.0 videotestsrc ! waylandsink
