rpi: add a Dispmanx renderer
Dispmanx is the prorietary display API on the Raspberry Pi, which
provides hardware compositing. Every visible surface is assigned a
Dispmanx element, and the hardware or firmware will do all compositing
onto screen. The API supports translation, scaling, flips, discrete
rotations in 90-degree steps, alpha channel on the surfaces, and
full-surface alpha on top.
Previously, Dispmanx capabilities were used via the weston_plane
mechanism, where surfaces were assigned to planes when possible, and
otherwise transparently falling back to GLESv2 compositing. Because we
have no way to use the same memory buffer as a GL texture and a Dispmanx
resource, we had to prepare for both. In the worst case, that means one GL
texture, and two (double-buffered case) Dispmanx resources, all the size
of a whole surface, for all surfaces. This was eating memory fast. To
make things worse (and less slow), the wl_shm buffer was kept around,
since it was copied to either a texture or a resource as needed. This
caused all clients to need two buffers. In a Dispmanx-only renderer, we
can drop the GL texture, and we can release wl_shm buffer immediately
after the first copy, so clients become effectively single-buffered. So
from the worst case of 5 buffers per surface, we go down to 3 or just
2 (single-buffered Dispmanx element, one wl_shm buffer in the client)
buffers per surface.
As this will replace the GL renderer on rpi, we cannot fall back to the
GLESv2 compositing anymore. We lose arbitrary surface rotation, but we
lose also the GL fallback, which caused glitches.
This patch depends on new RaspberryPi firmware. Older firmware may not
render ARGB surfaces correctly, solid color surfaces maybe cause a
performance hit, and the output may completely fail in case the firmware
does not fall back internal off-line compositing properly as needed.
This new rpi-renderer support surface translation and scaling, but not
rotation or transpose (not even in 90-deg steps). In theory, 90-deg step
surface rotation is possible to support. Output transformations are
supported, but flipped variants do not seem to work right.
As a detail, menus and other surfaces that are simply translated with
respect to another surface caused falling back to the GL renderer. The
rpi-renderer handles them directly.
This patch only adds the new renderer, but does not hook it up into use.

compositor: add capability CAPTURE_YFLIP
Both GL and pixman renderer (pixman probably only because GL did?)
return the screen capture image as y-flipped, therefore Weston y-flips

(non-flipped) screen captures, and does not need an y-flip.
Add a capability flag for y-flip, which the rpi-renderer will not set,

The wcap recording code needs yet another temporary buffer for the
non-flipped case, since the WCAP format is flipped, and the code

Mesa's eglSwapBuffers() waits for the frame event from the previous

When a sub-surface contains an EGL widget, and the commit mode is
synchronized, the frame events will not be delivered to EGL until the
parent surface gets committed. Therefore rendering the EGL widget twice
would lead to a deadlock.
When the window is being resized, we need to force a repaint of the EGL
widget, too, to make the whole window consistent. For that, we need to
make sure the frame event from the previous eglSwapBuffers() actually
arrives.
This patch adds an extra wl_surface.commit(parent), when the window is
being resized, which should guarantee, that the previous eglSwapBuffers
gets its event.
To properly handle an EGL widget in a sub-surface, running in its own
thread, the EGL widget's automatic updates should be paused before
sending the extra wl_surface.commit(parent). A natural place for the
pause would be in the widget's resize hook. However, wl_surface.commit
cannot be called right after resize hooks, because it would commit new,
incomplete surface state. Therefore this patch is not enough for

- eglSwapInterval(0) is implemented, and therefore eglSwapBuffers never
blocks indefinitely, or
- toytoolkit has a workaround, that guarantees that eglSwapBuffers will
return soon, when we force a repaint on resize.
Otherwise the demo will deadlock.
The code is separated into three sections:
1. The library component, using only EGL, GLESv2, and libwayland-client
APIs, and not aware of any toolkit details of the parent application.
This runs independently until the parent application tells otherwise.
2. The glue code: a toytoolkit application widget, who has its own

Toytoolkit applications have not had a possibility to change the input
region. The frame widget (decorations) set the input region on its own

widget_input_region_add() to set a custom input region.

shell: keyboard focus and restacking fixes for sub-surfaces
The shell needs to redirect some actions to the parent surface, when
they originally target a sub-surface. This patch implements the
following:
- Move, resize, and rotate bindings always target the parent surface.
- Opacity (full-surface alpha) binding targets the parent surface. This
is broken, because it should change the opacity of the whole compound
window, which is difficult to implement in the renderer.
- click_to_activate_binding() needs to check the shell surface type from
the main surface, because sub-surface would produce SHELL_SURFACE_NONE
and prevent activation.
- Also activate() needs to check the type from the main surface, and
restack the main surface. Keyboard focus is assigned to the original
(sub-)surface.
- focus_state_surface_destroy() needs to handle sub-surfaces: only the
main surface will be in a layer list. If the destroyed surface is
indeed a sub-surface, activate the main surface next. This way a
client that destroys a focused sub-surface still retains focus in the
same window.
- The workspace_manager.move_surface request can accept also
sub-surfaces, and it will move the corresponding main surface.
Changes in v2:
- do not special-case keyboard focus for sub-surfaces
- fix surface type checks for sub-surfaces in shell, fix restacking of
sub-surfaces in shell, fix focus_state_surface_destroy()
Changes in v3:
- Renamed weston_surface_get_parent() to
weston_surface_get_main_surface() to be more explicit that this is
about sub-surfaces
- Fixed move_surface_to_workspace() to handle keyboard focus on a
sub-surface.
- Used a temporary variable in several places to clarify code, instead
of reassigning a variable.
- Fixed workspace_manager_move_surface() to deal with sub-surfaces.

compositor: introduce sub-surfaces
Implement the basic protocol for sub-surfaces:
- expose wl_subcompositor global interface
- error checking on protocol calls
- associate a parent wl_surface to a sub-surface
- introduce the sub-surface role, which is exclusive
- an implementation of the wl_subsurface interface
- allow nesting of sub-surfaces
- proper surface transformation inheritance from parent to sub-surfaces
- two different modes of wl_surface.commit for sub-surfaces
- hook sub-surfaces up to repaint by modifying the repaint list code
Struct weston_subsurface is dynamically allocated. For sub-surfaces, it
is completely populated.
For parent surfaces, weston_subsurface acts only as a link for stacking
order purposes. The wl_resource is unused, parent_destroy_listener is
not registered, the transform is not linked, etc.
Sub-surfaces are not added directly into layers for display or input.
Instead, they are hooked up via the sub-surface list present in parent
weston_surface. This way sub-surfaces are inherently linked to the
parent surface, and cannot be displayed unless the parent is mapped,
too. This also eases restacking, as only the parent will be in a layer
list. Also, only the main surface should be subject to shell actions.
The surface list rebuilding in weston_output_repaint() is modified to
process sub-surface lists, if they are non-empty. The sub-surface list
always contains the parent, too, unless empty. The collection of
frame_callback_list is moved to a later loop, to streamline the surface
list rebuild functions.
Features still lacking are:
- full-surface alpha support for compound windows
Changes in v2:
- fix a bug in surface mapping: commit a sub-surface would cause the
main surface to never be mapped.
- remove debug printfs
- detect attempt of making a surface its own parent
- always zero-alloc weston_subsurface
- apply wl_subsurface.set_position in commit, not immediately
- add weston_surface_to_subsurface()
- implement sub-surface commit modes parent-cached and independent
- implement wl_subcompositor.destroy and wl_subsurface.destroy
Changes in v3:
- rebased, and use the new transform inheritance code
- squashed the commit "add sub-surfaces to repaint list"
- fixed a buffer reference leak in commit_from_cache()
- Rewrite the sub-surface destructor code, and make it leave the
wl_subsurface protocol object inert, if one destroys the corresponding
wl_surface.
- replaced set_commit_mode with set_sync and set_desync
- allowed sub-surface nesting, and fixed repaint accordingly
- implemented nested sub-surface commit modes
- Made the sub-surface order changes from wl_subsurface.place_above and
.place_below to be applied when the parent surface state is applied,
instead of immediately. This conforms with the protocol specification
now.

protocol: add sub-surfaces
Add protocol for sub-surfaces, wl_subcompositor as the global interface,
and wl_subsurface as the per-surface interface extension.
This patch is meant to be reverted, once sub-surfaces are moved into
Wayland core.
Changes in v2:
- Rewrite wl_subcompositor.get_subsurface description, and move mapping
and commit details into wl_subsurface description. Check the wording
in wl_subsurface.set_position description.
- Add wl_subsurface.set_commit_mode request, and document it, with the
commit_mode enum. Add bad_value error code for wl_subsurface.
- Moved the protocol into Weston repository so we can land it upstream
sooner for public exposure. It is to be moved into Wayland core later.
- Add destroy requests to both wl_subcompositor and wl_subsurface, and
document them. Experience has showed, that interfaces should always
have a destructor unless there is a good and future-proof reason to not
have it.
Changes in v3:
- Specify, that wl_subsurface will become inert, if the corresponding
wl_surface is destroyed, instead of requiring a certain destruction
order.
- Replaced wl_subsurface.set_commit_mode with wl_subsurface.set_sync and
wl_subsurface.set_desync. Parent-cached commit mode is now called
synchronized, and independent mode is desynchronized. Removed
commit_mode enum, and bad_value error.
- Added support for nested sub-surfaces.

input: Move surface picking into the pointer grab focus callback
Currently the core input code does surface picking before calling into
the focus callback of the current grab. Not all grabs need to pick a
surface however, so we're doing work we don't have to in those cases.
For example, the shell move and resize grabs don't need to pick and the
default grab in implicit grab mode doesn't either.
With this change, the pointer grab mechanism is now very simple:
the focus callback is called whenever the pointer may have a new focus,
the motion callback is called whenever the pointer moves and
the button callback whenever a button is pressed or released.

input: Get rid of grab focus concept
This was another complication that we had to have to support the
split between libwayland-server and weston. Different grabs want to send
events relative to different surfaces at different times. The default
grab switches between sending coordinates relative to the 'current' surface,
that is the surface the pointer is currently above, or the 'clicked'
surface, in case of an implicit grab.
The grab focus was set by the grab implementation and the core input code
would transform the pointer position to surface relative coordinates for the
grab focus and store in grab->x/y.
Now we can just let the grab implementation transform the pointer
coordinates itself, leaving the implementation free to transform
according to whichever surface it wants. Or not transform at all if
it doesn't need surface relative coordinates (like the shell move and resize
grabs).

input: Remove 'current' and related fields from weston_pointer
The current surface field was used to track the surface the pointer was

regardless of implicit or explicit grabs. The main purpose was to restore
the default grab when another grab terminated. We can now just repick in
that case and avoid keeping that state around, with the destroy listener
overhead that involves.
There was one other use case - we used to optimize out calls to
weston_pointer_set_focus() if the focus didn't actually change. We can
still do that, but we have to do that in the default_grab_focus() handler
and compare against weston_pointer->focus instead.
