Fixes#933
On startup, we'd set the cursor to "text" but we wouldn't store that as
our cursor so when the mouse was unhidden, we'd go back to "default".
This PR changes it so that on surface startup we set and store the
"text" cursor so as the cursor hides/shows it reverts to the proper
value.
This adds the gtk-titlebar option, which allows you to toggle the GTK
titlebar on (default) and off.
Under some circumstances (e.g. tiling WMs with titlebars enabled), one
may wish to disable the GTK titlebar/CSD for aesthetic reasons. This
allows you to do that.
Fixes#920.
Fixes#882
This hooks up all the GTK.IMContext things properly so that we support
switching input methods, popups, etc. This should improve our support
for asian languages, emoji input, etc.
In practice, the primary and selection clipboards are treated exactly
the same, but this allows OSC 52 sequences to use either 's' or 'p' as
the clipboard target.
This enables shifted alt-prefixed keys, such as `shift+alt+.` on
US standard becoming `M->`. To do this, we needed to fix a few bugs:
(1) translation mods should strip alt even if other mods are set
(2) AppKit translation event needs to construct new characters with
the translation mods.
(3) Alt-prefix handling in KeyEncoder needs to allow ASCII utf8
translations even for macOS.
Fixes#872
In #867 we fixed macos-option-as-alt, but unfortunately AppKit ALSO does
some translation so some behaviors were not working correctly.
Specifically, when you had macos-option-as-alt set, option+e would
properly send `esc+e` to the pty but it would ALSO set the dead key
state for "`" since AppKit was still translating the option key.
This commit introduces a function to strip alt when necessary from the
translation modifiers used at the AppKit layer, preventing this
behavior.
Instead of making a separate enum that must be translated from the
ClipboardRequest type, simply re-use ClipboardRequest to determine the
clipboard confirmation reason.
Use the .text field of the enum as the default value of the mouse shape
instead of renaming .default. Store the default value as the current
value for use in subsequent commits
