Support for non-PNG types is optional in the spice agent, so we should
avoid sending those if PNG is available.
Currently, the spice VDAgent supports only PNG and BMP formats.
To start a clipboard incr transfer the client has to delete the INCR
window property as the reply to the selection. This deletion generates a
property change event with the type delete, errornously triggering the
incr processing of the data. This patch corrects this by ignoring
property deletions.
Instead of damaging the entire surface when rendering a cursor move,
we can use the EGL_KHR_swap_buffers_with_damage extension to only
damage the part of the window covered by the cursor. This should
reduce the cursor movement latency on Wayland.
We previously used strstr, which can be prone to false positives when
the name of one extension is a substring of another extension.
This commit creates the helper function util_hasGLExt, which asserts
that the substring found in extension list is bounded by either spaces
or the beginning/end of the string.
Using util_cursorToInt messes with the error tracking for normal movements,
and is not necessary since we are computing an absolute position on the
client window.
Instead, we should pass doubles directly to display servers and let them
decide how to best handle them. For example, XIWarpPointer accepts doubles
directly.
This prevents the host cursor from moving into another window in capture
mode, solving the problem of input going to an overlapping window in
capture mode, and also preventing loss of focus with focus_follows_mouse.
Currently, (un)grabPointer is used both for tracking/confining the mouse
in normal mode, as well as entering/exiting capture mode. This makes it
impossible to use separate cursor logic for capture mode, which is needed
to deal with overlapping windows for the Wayland backend.
This commit creates separate (un)capturePointer for entering/exiting
capture mode. There should be no behaviour changes.
This adds a new method to the display server interface to allow the
application to notify the ds when there is a guest cursor position
update along with the translated local guest cursor position. This makes
it possible for the display server to keep the local cursor position in
sync with the guest cursor so that window leave events can be detected
when the cursor would move into an overlapping window.
Wayland currently just has a stub for this, and the X11 implementation
still needs some minor tweaking.
Due to the logic in the event loop property events may get filtered out
that were clipboard related. This changes ensures the clipboard event
handler code gets to run first avoiding this issue.
The clipboard atoms may not exist yet and as such we must create them if
this is the case. Failure to do so results in `SEL_DATA` being zero
breaking the clipboard paste mechanics
This commit fixes the -Wmissing-field-initializers warning, which can only
be disabled with a pragma. GCC wants us to Initialize libdecor reserved
fields, which requires knowing how many reserved fields there are.
This is an implementation detail, and so we can only disable the warning.
This also fixes -Wincompatible-pointer-types, which is an actual bug.
If the window manager does not support the motif hints then fallback to
creating a utility window, do not do both. A utility window is a
sub-optimal fallback as it may prevent the application being shown in
the taskbar or as a running application as has been reported on KDE.
Using the first two valuators present in the event is incorrect. Events
with only one valuator set, such as those sent by the Xorg evdev driver
when the mouse moved along one axis only, were being discarded. On the
other hand, mice with multiple scroll wheels may be able to emit events
with two scroll wheel valuators set.
The XInput2 specification is light on details, but "Rel X" and "Rel Y"
appear to be the de facto standard names for the motion valuators. If
valuators with those labels are not found, fall back to using valuators
with numbers 0 and 1.
Due to the confusing nature of the x11 protocol, bit_gravity and
win_gravity are not what they appear to be. These do not describe the
window position but rather the pixels/subwindows when the window is
resized. Instead set the gravity via the WM_SIZE_HINTS property which
all modern window managers should respect.
This fixes the fullscreen and likely borderless issue too that people
have been reporting on X11 under gnome. Thanks to tdb in discord for
spotting the error.
The only addition to v4 was `wl_surface_damage_buffer`, which we do not
use.
This change should allow running on more compositors (even though v4 is
already old -- 5 years now).

We don't necessarily need `wl_output.release`, which is the only
addition in v3.
This allows Looking Glass to run on Ubuntu 20.04 without having to go
difficult lengths to acquire newer Wayland packages. Since 20.04 is an
LTS release, this seems worthwhile for the small amount of complexity
this introduces.

This was missed when splitting up wayland.c into multiple modules.
This commit also drops the useless #include <SDL2/SDL.h>, bringing
SDL removal one step closer.
If the scale factor of an wl_output changes while the client is running,
the maximum scale factor is not updated. This may result in incorrect
scaling.
Therefore, when the scale factor is changed, we should generate a
resize event.
The Wayland display server is getting unwieldy due to the sheer size.
To make it easier to edit in the future, I split it into many components
based on logical boundaries.
This is enabled on default. Specify wayland:warpSupport=no to disable it,
which may be useful on certain compositors that do not warp when the
pointer is confined.
