Simplify RGB shader code and split off common code that could be reused.
This is preparatory work for YUV shaders.

Make weston_surface::texture and ::surface an array, while keeping

weston_compositor_init is always called late because most
implementations can't initialise GL until fairly late in the game.
Split it into a base version with the same name, followed by
weston_compositor_init_gl which can be called later on.
This simplifies compositor-wayland, which no longer needs a separate
global handler just for wl_seat.

notify_modifiers will now synchronise Weston's internal state with the
XKB state, and send a modifier event if necessary. This eliminates the
need for update_modifier_state to have a return value at all.
Signed-off-by: Daniel Stone <daniel@fooishbar.org>
If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit. Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.

X11 has a set of eight modifiers which we want to represent. Cache
their indices when we create a weston_xkb_info, so we can use this from
compositor-x11 to keep the state synchronised exactly between the host X
server and a nested Weston instance.

When the focus changes, wl_keyboard_set_focus (and, as an added bonus,
wl_pointer_set_focus) will now send wl_keyboard::modifier events for us
if we store the modifier state in the right place, so we don't have to
worry about that anymore.

This is the point where we have just finished rendering the new scene
but before we swap it to the front buffer. At this point, the
output->previous_damage region exactly corresponds to what was just
renders, as compared to previous frame.
We start tracking which hardware plane a surface is displayed on, which
lets us avoid generating damage when a hardware overlay/cursor is moved
around.
EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

We use the selection signal to get a callback when somebody sets a
selection (including the X server proxy) and then copy the contents
of the first mime type. If the selection is cleared (when the client
dies), we set a new selection with that contents.
These keymap events communicate the keymap from the compositor to the
clients via fd passing, rather than having the clients separately
compile a map.

This allows backends to generate their own keymaps and pass them in for
use rather than always forcing a single global keymap, which is
particularly useful for nested compositors.
Signed-off-by: Daniel Stone <daniel@fooishbar.org>
In practice this doesn't mean much right now, since they all just take
an extra reference on the global keymap.

Instead of using a uint32_t for state everywhere (except on the wire,
where that's still the call signature), use the new
wl_keyboard_key_state enum, and explicit comparisons.

Similar to how we deal with modifiers, also add LED handling to the core
input code, with a callout into the backends to update them when they
change.

When we update the modifier_state used for Weston bindings, derive this
from the XKB modifier state, rather than a hardcoded mapping of physical
keys to modifier state.

As we need to keep a separate state for every seat (i.e. keyboard
interface) rather than a compositor-global state.

This event lets the compositor inform clients of the canonical keyboard
modifier/group state. Make sure we send it at appropriate moments from
the compositor, and listen for it in clients as well.

Here we create a new client/compositor interface in weston to allow
clients to report their x/y cursor position to the compositor. These
values are then used to center the zoom area on this point. This
is useful for everyone, especially people who are visually impaired.
