The plan is to concencrate size computations as part of the frame clock
dispatch, meaning we shouldn't do it synchronously in the present()
function.
Still, in Wayland, and maybe elsewhere, it is done in the present()
function, e.g. when no state change was made, but this will eventually
be changed.
Mapping a surface under Wayland is an asynchronous process, where one
creates a surface and commits an initial state without having drawn
anything, then waiting for a configuration, which then is acknowledged
and content is painted and committed. Not until having received this
configuration is a surface actually mapped, so wait with setting the
mappedness until this.
These positions are not guaranteed to be in a specific order when linked
into the final GPU program. They need to be specified so that our code
in gskglrenderer.c can use known positions for them to match up with
our GskQuadVertex.
This fixes the GL renderer on macOS's OpenGL shader compiler.
Fixes#3420
This broke when we started using GDK_PROFILER_CURRENT_TIME for
timekeeping - that gets defined to 0 when we're building without
sysprof, so we can use it to make such determinations. Go back
to using g_get_monotonic_time().
Fixes: #3438
This fixes an issue where we would ignore events with Y delta
and no X delta while scrolling due to a typo when checking for
any delta.
This fixes deceleration of kinetic scrolling on the macOS backend.
Fixes#3418
On the macOS OpenGL implementation, the use of noise2 as a
function within the glsl shader collides with the builtin noise2 of a
different signature.
This changes the name to something similar (noize2) so that we
do not risk colliding names when linking.
With this commit, the shadertoy alienplanet demo works on mac
OpenGL (albeit still with the Cairo renderer).
Catch the error when it happens, so that we can emit a specific and more
helpful error message.
Also verify that all branches in the code now do indeed set a proper
GError when they fail, so that the final catch-all is no longer needed.
Instead, assert that the error is set so that we catch future code
additions early that do not set the GError.
This ensures that we don't leak window references inside the action muxer.
Otherwise, we risk not disposing the windows upon gtk_window_destroy()
and blocking the main loop from quitting.
Fixes#3419
We need to keep this consistent so that we can look things up
faster in other places. Therefore, just take the hit here and clear
the entire list ensuring prev/next poniters are cleared.
This comes complete with animation support. For a good time, try:
@keyframes conic {
100% { background-image: conic-gradient(from 1turn, red, lime, blue, yellow, red); }
}
window {
background-image: conic-gradient(red, lime, blue, yellow, red);
animation: conic infinite linear 5s;
}
