The case when `quit-after-last-window-closed=true` and
`quit-after-last-window-closed-delay=null` was broken because control
gets stuck inside `g_main_context_iteration` and never returns to our
code. In that case add a 0ms timer that will return control flow from
GLib back to our code so that we can quit.
Fixes#2039
There are scenarios where this configuration looks bad. This commit
introduces some heuristics to prevent it. Here are the heuristics:
* Extension is always enabled on alt screen.
* Extension is disabled if a row contains any default bg color. The
thinking is that in this scenario, using the default bg color looks
just fine.
* Extension is disabled if a row is marked as a prompt (using semantic
prompt sequences). The thinking here is that prompts often contain
perfect fit glyphs such as Powerline glyphs and those look bad when
extended.
This introduces some CPU cost to the extension feature but it should be
minimal and respects dirty tracking. This is unfortunate but the feature
makes many terminal scenarios look much better and the performance cost
is minimal so I believe it is worth it.
Further heuristics are likely warranted but this should be a good
starting set.
Add `window-padding-top`, `window-padding-bottom`,
`window-padding-left`, and `window-padding-right` options. The
`window-padding-x` and `window-padding-y` options will override the
individual options.
Instead of "polling" to see if a quit timer has expired, start a single
timer that expires after the confiugred delay when no more surfaces are
open. That timer can be cancelled if necessary.
This patch fixes#2010 by implementing `quit-after-last-window-closed`
for the GTK apprt. It also adds the ability for the GTK apprt to exit
after a delay once all surfaces have been closed and adds the ability to
start Ghostty without opening an initial window.
Fixes#2018
We should avoid mouse reports when we have a key event without an
associated mouse event (button or move). This is how xterm behaves and
we should match it.
Our approach to doing this is very hacky so I commented why and we can
hopefully clean all this up in the future.
