Need to include wlr/config.h before using the various WLR_HAS_xxx defines

Make X11 fully optional

The xcb_connection_t instance that is used here comes from
XGetXCBConnection(), is created by XOpenDisplay(), and is owned by the
returned Display*. Calling xcb_disconnect() directly on it leads to
various use-after-frees during shutdown, as reported by valgrind. The
first one of the about 30 errors is:

Normally, one would expect this to crash during XCloseDisplay() when
xcb_disconnect() is called again and frees the same data again (glibc would
detect a double free). However, XCloseDisplay() tries to clean up some internal
caches first for which it has to send requests to the X11 server (e.g. the
XFreeGC() above). This fails since the file descriptor was already closed,
which causes an IO error. Xlib's _XDefaultIOError() handles this by printing an
error message and calling exit(1).
Thus, the only symptom of this problem was compositors exiting
mid-shutdown and printing an error message:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 6 requests (6 known processed) with 0 events remaining.

- xcb_query_pointer_reply return value needs to be freed
- call XCloseDisplay
- remove wl event_source
|
|
This makes the hardware cursor code a less efficient. Can be
fixed with a GLES3 renderer.
|
|
|
|
This allows raw GL calls outside wlr_renderer to be removed.

The current mode was set to NULL to abuse it as state variable
persisting DRM suspend/resume, this results resulted in a segfault on
normal DPMS cycle.
This reverts that change and uses the wlr_output enabled variable, which
also persists and makes more sense.
|
|
If there is no current mode, set outputs to dpms off in drm resume.
Sets current mode to null on disable to ensure this can be checked.
|
|
Make wlr_render_with_matrix use alpha
|
|
so we can use the alpha channel to e.g. blend in textures
|
|
destroy frame timer in headless output
|
|
|
|
If input_event is null (e.g. if backend_start has not been called yet)
wl_event_source_remove will result in a null deref.
