This is exposed in the GUI as a new "CiTrace Recording" widget.
Playback is implemented by a standalone 3DS homebrew application (which only runs reliably within Citra currently; on an actual 3DS it will often crash still).
It provided a large increase in complexity of the logging system while
having a negligible performance impact: the usage patterns of the ring
buffer meant that each log contended with the logging thread, causing
it to effectively act as a synchronous extra buffering.
Also removed some broken code related to filtering of subclasses which
was broken since it was introduced. (Which means no one ever used that
feature anyway, since, 8 months later, no one ever complained.)
In various menu options letter cases were not consistent. This was also
the case within various debugging widgets. This attempts to make letter
cases consistent, but it is of course a matter of opinion which way is the
correct one.
Only allow manually setting focus to the rendering widget when in Single Window mode. Apply this behavior to when changing the mode while an app is running.
By default widgets are set to the focus policy Qt::NoFocus which disallows manually focusing it. Changing the policy to allow clicking the widget to set focus to it allows for keyboard input when not rendering to a popout window. This commit also sets focus to the widget when showing it.
Fixes issue #158.
The window title is none of the emulation core's business. The GUI code is free to put whatever it wants there.
Providing properly thread-safe window title getters and setters is a mess anyway.
