Instead of just passing major/minor, pass them twice, once for GL and
once for GLES. This way, we don't need to check for GL and GLES
separately.
If something is supported unconditionally, passing 0/0 works fine.
That said, I'd like to group the arguments somehow, because otherwise
it's just a confusing list of numbers - but I have no idea how to do
that.
We want critical GL debug messages to be critical, so that the testsuite
sudokus itself when they appear.
This is relevant in particular for GLES warnings in the GLES runner,
because its warnings can cause crashes on GL drivers less forgiving than
Mesa.

When destroying the EGLSurface or GLXDrawable of a GdkSurface, make sure
the current context is not still bound to it.
If it is, clear the current context.

We now have a boolean setting that determines whether the high-contrast
theme should be used. Support it by automatically setting the existing
`gtk-theme-name` and `gtk-icon-theme-name` properties when enabled.
With that, it is no longer necessary to change the regular theme settings
for high-contrast, so toggling between high-contrast and a non-default
theme finally works reliably.
It makes sense to connect the begin/update/end events
for touchpad swipes and pinches in a sequence. This
commit adds the plumbing for it, but not backends
are setting sequences yet.
We finish the write to the output stream long after the stream has been
closed, so we want to keep the event handler around to do just that.
Instead, remove the handler on finalize.
The OutputStream needs to write a 0 byte end of stream Property. We need
to track if that has been written, and we do that with that new
property.
We also use that property to always request flushes when the stream is
being closed, so that we don't wait for another flush() call.
We need to be very careful when writing data, because if we aren't, sync
functions will be called on the output stream and X11 does not like that
at all.
I saw this coming across through a ffi boundary in Sysprof, and we wanted
to keep most things within GDK using native marshalling to improve
profiler results when frame pointers are not used.
.. when creating the surface (with the HWND associated with the
newly-created surface) as well as destroying the surface (with NULL,
since the HWND is going to be destroyed), so that we can tie the EGL
calls to the HWND that we want to do the EGL stuff.
In some circumstances (e.g. activating with a stylus something that
closes a window), we can receive zwp_tablet_tool.proximity_out without
receiving a zwp_tablet_tool.up beforehand.
In those cases, we are not expecting neither .up nor .button, so
reset the stylus device button modifiers on proximity_out.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4103
We are looking up the seat logical pointer modifiers (i.e. the wl_pointer),
not the ones for the tablet tool device. This breaks accounting further
along in GTK leaving stuck implicit grabs.

Update the functions that were updated in the previous commit to have all
GdkSurface variables named as 'surface' instead of the GTK-3.x-era window, to
make things more consistent across the board. Also fix formatting a bit.
Make the toplevel surface respond to size computations unless it is just being
created, or maximized, made fullscreen or underwent an AeroSnap operation.
This will ensure that the surface size is properly computed in time, so that
surfaces can be resized as needed.
This will fix issues 3728 and 3799.
As far as I can tell, the code here is redundant and probably ended up
this way for historical reasons. A drag surface without
`->is_drag_surface` would be created if `gdk_display_create_surface`
were called with `GDK_SURFACE_TEMP`, but drag surfaces never seem to be
created that way.
In `gtk4-demos`, drag and drop and popovers seem to be working normally
with this.
Ensure that we take the DPI scaling into account so that surfaces will
be placed at their correct positions upon an AeroSnap operation on HiDPI
displays.
Also, use the X coordinate of the surface as-is during snap up so that
we do not inadvertently move the surface to the very left. Also fix the
AeroSnap indicator drawing for snap up so that it is drawn at the
correct places.
Since we are updating these functions, make the old GdkWindow-era
variable names to match better the names we use nowadays.
Use the debug envvar 'GDK_DEBUG=gl-egl' to determine whether we want to try to
initialize EGL first before trying WGL, as a means for people to more easily
enable EGL support on Windows to test EGL there (such as to debug the shaders,
for instance)
This will clean up the EGL code in GDK-Win32, as well as fixing crashes caused
by using an invalid EGL context in gdk_gl_context_make_current() as we did not
store up the EGL context in the correct place (lost during the transition to
the common EGL initialization code).
On the Windows/libANGLE side, the initialization of EGL has now fully moved to
the common code in GDK, but we will still default on WGL for now. Help is
really appreciated for fixing the shaders on libANGLE!
We need to ensure that gdk_display_get_egl_display() is available even if EGL
is not enabled in the build, so that things will continue to link and work.
For builds without EGL, just return NULL.
This will port the EGL code in GDK-Win32 to use the common GDK code to
initialize EGL. However, at the current state, although EGL is
correctly initialized, this code is disabled for now since
gdk_gl_context_make_current() fails as the shaders do not work for EGL
via libANGLE on Windows.
We can now clean things up in gdkglcontext-win32-egl.c as a result.
Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
Instead of using GL_BACK, use GL_BACK_LEFT, because the spec demands
this (many drivers don't).
Also move the call from the GDK backends into the GLContext code, as
this is a generic EGL issue (nvidia being the main driver in need of
this call, see 9c4c4eaaa1 for a longer
discussion).
Fixes#4402
gdk_display_create_gl_context only returns NULL when there is
an error set or asserts/aborts. So nullalbe annotation isn't needed.
Similar to 53312cf696
This is an alternative to gdk_surface_create_gl_context() when the
context is meant to only draw to textures.
This is useful in the testsuite or in GStreamer or with GLArea,
basically whenever we want to do GL stuff but don't need to actually
draw anything on screen.
A bunch of code will need to be updated to deal with context->surface
being NULL.
Make it use gdk_memory_texture_from_texture().
Also make gdk_memory_format_alpha() privately available so that we can
detect if an image contains an alpha channel.
This is a port of the fix in the quartz backend to the new macOS backend.
From the original commit:
In macOS-12.sdk CGContextConverSizeToDeviceSpace returns a negative
height and passing that to CGContextScaleCTM in turn causes the cairo
surface to draw outside the window where it can't be seen. Passing the
absolute values of the scale factors fixes the display on macOS 12 without
affecting earlier macOS versions.
