This fixes once and for all the core issue of different Godot `keycode`s
released from the same raw XKB keycode.
The `InputEventKey` `keycode` value _should_ map to the "unmodified"
key, but unfortunately there's an ambiguity with their encoding for
"special" keys ("delete", "insert", etc.), in witch they ignore their
unicode representation. This means that a key that is special when plain
but a character when modified would never be properly picked up, so we
do indeed change its keycode. As a consequence of this exception, some
Godot keys never receive release events and get "stuck".
This patch adds an extra check through an `HashMap` to "unstuck" keys
that changed while having the same keycode.
I also could not resist simplifying a bit the regular key event
generation method but this makes things more consistent and predictable
IMO.
There were two edge cases in the frame waiting logic (aka manual frame
throttling or emulated vsync) which would cause the editor to stall in
one way or another:
1. Waiting right after starting the editor would cause a deadlock
between both threads until something happened in the Wayland event
queue, in turn unblocking the Wayland thread and kickstartin the whole
thing;
2. Starting the editor (and probably other long-loading stuff) without
low consumption mode would suspend the window and never commit its
surfaces, thus never signaling the compositor that we want frame events.
We should only include the vendored headers for Wayland and libdecor-0 when
we use `so_wrap`, i.e. when we *don't* build against system libraries.
The libdecor-0 pkg-config file includes the `libdecor-0/` prefix already,
so its header should be included without it, and likewise in our so wrappers.
Fixes#102671.
The `keycode` field of `InputEventKey` is supposed to be "unshifted";
That is, what the key would output if no modifier keys were pressed.
This should match what's written on the key label, but `Key` enumerates
also all keypad keys, which require a modifier. We thus require some
extra checks for them.
Note that this can still allow "stuck keys", but that's an even deeper
problem.
Images don't have RIDs and this way of checking stuff broke the cursor
cache. Let's do like all other platforms and check the resource
reference instead.
Before, we would check both methods together, leading to loops.
Now we track the actual reason we suspended and only unsuspend when
that same reason triggers. For example, if we suspend because of the
suspended flag we'll unsuspend only because it got unset. Conversely, if
we suspend because of a timeout we'll unsuspend only if we get a new
frame event.
We do this because, while some compositors properly report a "suspended"
state (hinting us to stop repainting), most don't and we need a "safety
net" anyways as we do not want to constantly stay at 1fps (the max time
we'll wait before giving up) either.
The v1 version is deprecated and bound to be removed in the future from
all compositors. This patch adds a v1/v2 designator to everything
related to the protocol and prefers the v2 protocol if both are
available.
Additionally, renames the event handler to follow the Wayland interface
name, for consistency with the rest of the codebase.
Godot checks if there's Vulkan or GLES3 support.
If no support is found, it shows an error message.
However the code for this error message is left out when building with
opengl3=no
