When a surface is on a non-primary plane (overlay), we do not need to
keep the GL texture up-to-date, since we are not using it. Avoid calling
glTex(Sub)Image2D in that case, and accumulate the texture damage
separately.
This is especially useful for backends, that can put wl_shm buffers into
overlays.
The empty damage check has to be moved from surface_accumulate_damage()
into gles2_renderer_flush_damage(), because it really needs to check the
accumulated damage, not only the current damage. Otherwise, if a surface
migrates from a plane to the primary plane, and does not have new
damage, the texture would not be updated even for accumulated damage.

Instead of hardcoding drm-backend.so as the default if environment
presents neither Wayland nor X11, have a ./configure option to change
it. It still defaults to drm-backend.so, if not given.

Add the concept of debug key bindings, that are bindings that activate
debug features in the compositor. The bindings are added to a list in
the compositor, but the triggering them is left to the shell.
On the shell side, a global debug key binding is added. When the user
presses mod-shift-space, the shell will invoke the debug bindings based
on the next key press.
This also converts the debug shortcuts for repaint debugging, fan
repaint debugging and the hide overlays shortcut in compositor-drm to
use the new infrastructure.
Add a headless backend and a noop renderer, mainly for testing
purposes. Although no rendering is performed with this backend,
this allow some of the code paths inside Weston and shm clients
to be tested without any windowing system or any need for drm
access.
XKB provides keypad symbols in a separate namespace. We don't care
about the distinction, so map them to normal symbols before starting
processing.

Do not try to insert the input panel layer in the layer list when the
shell is locked in show_input_panels(). The layer will already be
insrted in resume_desktop() anyways.

The following sequence:
wl_surface::attach(s, b, 1, 2)
wl_surface::commit(s)
wl_surface::commit(s)
would actually result in the surface getting moved by (2,4) as the
pending attach delta wasn't reset on commit, only by another attach.
This only shows up on single-buffered surfaces.

Every single frame, we were calling the flush_damage handler in the
renderer. For GLES2 with subimage, this wasn't too bad as we'd never
call glTexSubImage2D, but without it, we'd upload the entire frame
through glTexImage2D every time.

In order to use XKB capabilities (as we do), the client must issue an
XkbUseExtension request:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Initializing_the_X_Keyboard_Extension
The reason this succeeds currently is that XOpenDisplay from Xlib does
this for us. But it is better not to rely on that, but do it explicitly
in XCB with the rest of the XKB init sequence.

Pressing ctrl-alt-o will cause the overlays to be hidden, but surfaces
will still be assigned to different planes. This helps with debugging
of repaint culling below surfaces in other planes.
Culling of the repaint of a surface behind an opaque surface on the
same plane was broken by commit 547149a9 [1]. The idea of that commit
is that the damage obscured by an overlay would remain on the primary
plane damage and be repainted when the overlay moved. However, in the
case the two surfaces are on the same plane, the opaque one is not
obscured, so it ends up being repainted.
This commit adds an opaque field to struct weston_plane, that is built
incrementally when accumulating damage. The opaque region of surfaces
on the same plane are removed from the plane's damage, restoring the
previous culling behavior. But since damage behind opaque region of
other planes is maintained, the bug solved in the mentioned commit is
not regressed.

We need to clamp or center on a per axis basis. If the window is wider
but the image is taller, we need to center horizontally but
clamp vertically. We can only do that if by combining the two
functions.
Clicking outside popups closes them except in case of a shell grab
(move, resize or rotate), in which case we move the parent window away
from under the popup. Instead, just end the popup in those cases.

Partial repaints have been broken since the introduction of the atomic
surface updates. The problem was that surface_commit would set the
geometry dirty flag unconditionally, causing transform updates on every
frame which would in turn cause weston_surface_damage_below() to damage
the whole surface area.
This patch changes this so that flag is only set if the pending buffer
has a different size, the location of the surface changed or the opaque
region changed.
Note that changing the opaque region will cause a full repaint of the
affected surface, because of the transform update.

The intended behavior is that a quick click (press and then release
within 500ms) just pops up the menu and doesn't select anything. Then
we can mouse around and and click to select an item. Alternatively, a
click and hold (ie press and release after 500ms) lets you press right
button, mouse down on the menu item you want and release to select it.
This is how menus work in most toolkits.
The handling in weston is fine, it's there to handle the case where
the button release happens outside any client window, since the client
doesn't get those events. If such a release happens late or we get a
second release outside the popup window we shut down the popup.
The problem is in toytoolkit, where we need to select the item if we
get a release within 500ms or if we get a second release. A second
release is the case where the first release came after 500ms and
didn't pop down the menu, and the second release event is from a click
on a menu item.

If clients don't set a cursor, they get whatever the last cursor was
before the pointer entered their window. That's a little confusing, so
set a pointer on enter to avoid that. The down-side is that simple EGL
isn't very simple anymore.

If we can find a boot_vga PCI GPU, we should prefer it over any other GPU
that is connected to the system. The boot_vga flag tells us that this GPU
is the primary system GPU.
This fixes problems on two-GPU-systems were the wrong GPU is used. It also
fixes systems were DisplayLink GPUs are available with lower IDs than PCI
GPUs (although, this seems unlikely).
Note that udev_enumerate guarantees that the entry-list is sorted. So for
systems that have platform-GPUs, these should almost always be reported
prior to hotpluggable (PCI, USB, ...) GPUs, as the kernel probes them
first.

By request on the wayland-devel mailing list, we could start collecting
useful writings here.
However, this is not meant to be a substitute to proper documentation,
though I understand it may very well become one. Better than nothing, I
guess, and hopefully helps in writing real documentation.
Feel free to add stuff.

Toytoolkit does not support setting opaqueness for anything else than
the immediate child widget of the frame widget. Backgrounds do not have
frames, so we need to poke it in manually.
This should allow Weston to paint the background without blending.
