GCAdapter::UseAdapter() reads s_is_adapter_wanted, which gets
initialized by config_guard.~ConfigChangeCallbackGuard(). So we must
wait until after destroying the config guard to know whether we have any
controllers set to GC Adapter.
Expanded the use of the lock mutex already used for loading the player's existing unlock status to guard against races involving the Achievements dialog window reading from data AchievementManager might be in the process of updating. The lock has been exposed publicly and the AchievementsWindow uses it in its UpdateData method, and anywhere else that might modify data used to render that window has also been wrapped with it.
AchievementManager now has a SetUpdateCallback method for providing a single universal callback for anytime something important changes in the achievement state, such as logging in/out, game load/close, or events such as achievement unlocks. AchievementsWindow sets this callback in its own init to its UpdateData method so that the AchievementsWindow gets updated when one of these changes takes place.
This widget is a tab in the AchievementsWindow that displays the player's current achievement progress: which achievements are locked or unlocked, and the progress of achievements that have progress metrics.
This widget displays a header on the AchievementsWindow dialog above the tabs that shows the currently logged in user (if there is one) and the game they are playing (if there is one).
1 ) When first opened, the (user selected) post process shader config widget would print the wrong values on the text label next to int range sliders. For example if the range was from 1 to 6, and the value loaded from the config was 1, the label would print 0 when first opened, to then start showing the correct value once the slider was first moved.
This mirrors the behaviour of the float slider code below:
```auto* const value_box = new QLineEdit(QString::asprintf("%f", m_config_option->m_float_values[i]));```
2 ) The defautl int slider value would also be set wrong on first load, as it was being divided by the slider max instead of the slider step amount (again, just like for the float implementation). This is a mistake I had made with my previous submission.
This doesn't need to be handled by translators, since they're not
user-displayed text or just don't need to be translated.
While we're at it, we don't need to copy each entry of the resulting
list.
Mesa (llvmpipe) only reports 4x MSAA, and doesn't report 2x (or 1x, but we implicitly add that). The old logic did not handle this correctly, causing selecting 4x to fail and fall back to None.
This also removes VideoUtils::GetAvailableAntialiasingModes, and thus VideoUtils entirely, as its only other function was removed in 1f74653501.
We can move the construction of the Diff instance into the body of the
if statement, so that we only construct this if the condition is true.
While we're at it, we can move the symbol description string into the
instance, getting rid of a copy. The function itself can also be const
qualified.
