Adds a comptime function to enable conditional compilation against
different GTK versions that have added new API calls in newer versions
of GTK.
Use this function to get fractional scaling information for GTK
surfaces, which is only available with GTK 4.12+.
Use glib-compile-resources to compile CSS style sheets and icons into
the Ghostty GTK binary. Makes for simpler access to icons and sets
things up for customizing the look of Ghostty with CSS in the future.
The CSS style sheets are blank for now so there will be no visual
changes.
This fixes an issue in that when running under X11, when a modifier key
is pressed, the modifier state will "lag" behind what should be current.
This is due to how X11 sends modifiers in events, i.e. it sends the
state from right before the key press, and does not include the effects
of the key press itself.
This is corrected by checking the X event queue directly for a pending
XkbStateNotify event (we mask this on modifiers), and setting the
modifiers off of that if we find one. If not, we fall back to the GDK
call.
This ensures that WM_CLASS is being set on X11, looks like this was
missed in #816 (not 100% sure if it always needs to be set in GDK or if
it's a side effect of us not using g_application_run).
This also adds the "x11-instance-name" config attribute to control the
instance name, which defaults to "ghostty" (or "ghostty-debug" on debug
builds).
* When using gtk as the backend, link libadwaita
* Update c.zig
* Use libadwaita's theme manager for gtk
* update the documentation for window-theme
* build: add libadwaita to the nix devshell
* forgot to properly import libadwaita
* apprt/gtk: adwaita style change
