Add GtkTextHandle This is a helper object to allow text widgets to implement text selection on touch devices. It allows for both cursor placement and text selection, displaying draggable handles on/around the cursor and selection bound positions. Currently, this is private to GTK+, and only available to GtkEntry and GtkTextView.

gtktexthandle: Update to gtk4 rendering/input GtkTextHandle was neglected by whoever removed the ::draw signal, leaving it entirely broken. Update to using GtkGizmo so we can implement snapshot of text handles. Input has received a revamp too, handling is done through a GtkGestureDrag and coordinate calculations simplified by storing the delta to the hotspot on ::begin instead of ::update, as this value is constant throughout the gesture. Widget state management on crossing events happens implicitly, so no longer needs to be done here. Last but not least, CSS has also been updated so handles are rendered at the correct size and proportion, and with the padding that code expects of it.

Update to using GtkGizmo so we can implement snapshot of text handles. Input has received a revamp too, handling is done through a GtkGestureDrag and coordinate calculations simplified by storing the delta to the hotspot on ::begin instead of ::update, as this value is constant throughout the gesture. Widget state management on crossing events happens implicitly, so no longer needs to be done here. Last but not least, CSS has also been updated so handles are rendered at the correct size and proportion, and with the padding that code expects of it.

popover: Fix memory management of popovers Popovers are strange in the sense that they aren't attached to a parent directly, they rely on the relative_to widget so the toplevel is shared, and when they have a parent, it is the toplevel itself, not relative_to. This also means that there are conditions where the popover loses it's parent, so they must survive unparenting. The previous code would be floating the last reference as soon as the parent is gone, but it was non-obvious who'd own that reference. So fix this situation by granting the ownership of popovers to their relative_to widget, an extra reference may be held by the toplevel when the popover has a parent, but the popover object will be guaranteed to be alive as long as the parent lives. This way, memory management of popovers is as hidden from the user as regular widgets within containers are, users are free to call gtk_widget_destroy() on a popover, but it'd eventually become destructed when relative_to is.

popover: Fix memory management of popovers Popovers are strange in the sense that they aren't attached to a parent directly, they rely on the relative_to widget so the toplevel is shared, and when they have a parent, it is the toplevel itself, not relative_to. This also means that there are conditions where the popover loses it's parent, so they must survive unparenting. The previous code would be floating the last reference as soon as the parent is gone, but it was non-obvious who'd own that reference. So fix this situation by granting the ownership of popovers to their relative_to widget, an extra reference may be held by the toplevel when the popover has a parent, but the popover object will be guaranteed to be alive as long as the parent lives. This way, memory management of popovers is as hidden from the user as regular widgets within containers are, users are free to call gtk_widget_destroy() on a popover, but it'd eventually become destructed when relative_to is.

texthandles: Keep state internally to avoid X overhead Handles now do sync X calls less often. As visibility state is kept, it now can move+resize+show handles at once instead of in separated steps.

handle_window->has_point = TRUE;
texthandle: Set a bigger input shape, covering the line height Now, even if the handles being rendered are small, the handle touch input shape will be as wide as the visible part of the rendered asset, and high enough to cover both the handle and the height of the line where the selection bound is. Also, make handles have the same virtual distance to the line top/bottom when a drag starts, so the handle doesn't jump to another line after a too short threshold.

texthandles: Use GtkWindow popovers API This offers the same behavior, but GDK_WINDOW_TEMP windows aren't used anymore, involving less translations from/to root coordinates, plus no glitches in having handles snap to content as windows move.

Add GtkTextHandle This is a helper object to allow text widgets to implement text selection on touch devices. It allows for both cursor placement and text selection, displaying draggable handles on/around the cursor and selection bound positions. Currently, this is private to GTK+, and only available to GtkEntry and GtkTextView.
