m_hover_label did not have checks if the mouse is in the same location.
This caused clickable URLs to be hidden.
Also shortened the label text to not be longer than half of the window.
The Qt style hints' color scheme can return ::Unknown, in which case we
still need to fall back to our 'old' method of using the luma component
of the background role color.
For Qt >= 6.5, the system theme can be determined reliably, so no
guesswork is needed. A fallback remains for Qt < 6.5, but it is
hacky and less reliable.
LibWebView now knows how to launch RequestServer and ImageDecoderServer
without help from the UI, so let's move ownership of these services over
to LibWebView for de-duplication.
We will want to re-inform WebContent of the system visibility state when
we create a new process after a crash. This changes the IPC to just send
the enum value directly, instead of a boolean, so that we can just store
that enum value directly on the ViewImplementation class.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
