* GAL: Dispose Renderer after running deferred actions
Deferred actions from disposing physical memory instances always dispose the resources in their caches. The renderer can't be disposed before these resources get disposed, otherwise the dispose actions will not actually run, and the ThreadedRenderer may get stuck trying to enqueue too many commands when there is nothing consuming them.
This should fix most instances of the emulator freezing on close.
* Wait for main render commands to finish, but keep RenderThread alive til dispose
* Address some feedback.
* No parameterize needed
* Set thread name as part of constructor
* Port to Ava and SDL2
* gtk: Add missing isMouseInClient check for hide-cursor
* ava: Add missing events and default isCursorInRenderer to true
This is necessary because we don't receive a initial PointerEnter event for some reason.
* Changed LastPlayed field from string to nullable DateTime
Added ApplicationData.LastPlayedString property
Added NullableDateTimeConverter for the DateTime->string conversion in Avalonia
* Added migration from string-based last_played to DateTime-based last_played_utc
* Updated comment style
* Added MarkupExtension to NullableDateTimeConverter and changed its usage
Cleaned up leftover usings
* Missed one comment
* Add hide-cursor command line argument
* gtk: Adjust SettingsWindow for hide cursor options
* ava: Adjust SettingsWindow for hide cursor options
* ava: Add override check for HideCursor arg
* Remove copy&paste sins
* ava: Leave a little more room between the options
* gtk: Fix hide cursor issues
* ava: Only hide cursor if it's within the embedded window
