This makes it clear that sending a signal a second time will force stop
Dolphin (which is useful in case the GUI is deadlocked or otherwise
unable to react to the signal).
Before this variable was an u8, which could theoretically result in desyncs with a large buffer(greater than 255*120/200=153) filled with blank inputs. If this could actually happen, i don't know. But this part of the code on its own looks like it could break.
A static var is not a good idea, when the value needs to be reset for every session. Also, the variable holds the data size, so it makes sense to set the data size, where the data is added.
This makes DolphinWX shut down cleanly, just like it would with
File->Exit when it receives a SIGINT, SIGTERM (Unix) or some signals
on Windows.
The default signal handler will be restored after a first shutdown
signal so a second signal will exit Dolphin forcefully.
When Movie was calling ChangeDisc, it was moving execution to
the host thread just to then make the host thread the CPU thread.
We can simply run the code directly on the CPU thread instead.
In TimeSplitters: Future Perfect, PerfQuery is used to detect
the visibility of lights and draw coronas. 25 points are drawn
for each light. However, the returned count was incorrectly
being divided by four leading to dim coronas.
Using 4x antialiasing was a workaround because of a bug where
antialiasing multiplied the PerfQuery results. This commit
fixes that bug too (but only for OpenGL).
The active codes normally get cleared when a game boots, because
LoadPatches gets called, replacing the codes from the previous game.
However, there were cases where LoadPatches doesn't get called, and
then codes from the previous game would be used for the current game.
This commit clears the codes on shutdown so that it doesn't matter
whether the boot process loads LoadPatches.
If banner loading fails once, it will very likely fail again.
Setting m_banner_loaded to true when banner loading fails
prevents LoadBannerFile from wasting time if it's called again.
Banner loading requires loading the file system, which takes a
noticeable amount of time, so this matters.
