2021-03-08Add: [Video] move GameLoop into its own threadPatric Stout
This allows drawing to happen while the GameLoop is doing an iteration too. Sadly, not much drawing currently can be done while the GameLoop is running, as for example PollEvent() or UpdateWindows() can influence the game-state. As such, they first need to acquire a lock on the game-state before they can be called. Currently, the main advantage is the time spend in Paint(), which for non-OpenGL drivers can be a few milliseconds. For OpenGL this is more like 0.05 milliseconds; in these instances this change doesn't add any benefits for now. This is an alternative to the former "draw-thread", which moved the drawing in a thread for some OSes. It has similar performance gain as this does, although this implementation allows for more finer control over what suffers when the GameLoop takes too long: drawing or the next GameLoop. For now they both suffer equally.
2021-03-08Codechange: don't set the window position when changing blitterMichael Lutz
There really is no need to make an extra call to the OS in these cases.

2021-03-08Remove: [Video] no longer draw in a threadPatric Stout
Drawing in a thread is a bit odd, and often leads to surprising issues. For example, OpenGL would only allow it if you move the full context to the thread. Which is not always easily done on all OSes. In general, the advise is to handle system events and drawing from the main thread, and do everything else in other threads. So, let's be more like other games. Additionally, putting the drawing routine in a thread was only done for a few targets. Upcoming commit will move the GameLoop in a thread, which will work for all targets.
2021-03-08Fix #8784: using alt+enter didn't update the fullscreen toggle visibly (#8820)Patric Stout
Basically, the window was not invalidated, so it was never redrawn. This made it look like it wasn't working, but it really was.

the video buffer.
2021-03-08Add: Option to (dis-)allow accelerated video drivers. (#8819)Patric Stout
The video drivers using the OpenGL backend are currently our only accelerated drivers. The options defaults to off for macOS builds and to on everywhere else. Co-authored-by: Michael Lutz <michi@icosahedron.de>

fullscreen.
2021-03-01Fix c4df0f95: bootstrap was only showing a black screen (#8788)Patric Stout
The bootstrap has the _switch_mode to SM_MENU, and never leaves this mode. Neither is it considered a modal window (while in some sense it really is). So .. we need to add another "draw anyway" exception, to make sure bootstrap is being drawn.

2021-02-28Add: settings to limit your fast-forward game speedPatric Stout
By default this setting is set to 2500% normal game speed.
2021-02-28Fix #8763: [OpenGL] Cursor sprite origin can be negative.Michael Lutz
2021-02-27Fix: [OpenGL] Don't use OpenGL on MESA software renderers.Michael Lutz
Performance in this case is worse than not using OpenGL, so just let OTTD fall back to a different video driver.

2021-02-24Codechange: [OSX] GameLoop is really more like MainLoopPatric Stout
MainLoop() is used to bootstrap OSX, where later a callback is done to GameLoop() to execute OpenTTD. All other video drivers don't need that, so what is in GameLoop is in MainLoop for all other drivers. This is rather confusing. So, instead, name GameLoop MainLoopReal to be more in sync with the other drivers.

2021-02-22Codechange: [SDL] Move dirty_rect to class scope.Michael Lutz
2021-02-22Codechange: [SDL2] Allow several places to hook into the SDL driverPatric Stout
This allows future subdrivers to use these to manage their own flow.
2021-02-22Codechange: [SDL2] Move functions and variables to class-scopePatric Stout
This allows future subdrivers to override them.
2021-02-22Codechange: [SDL2] Move SDLSurface code to its own functionPatric Stout
This increases readability, and allow future subdrivers to not use SDLSurface to draw.
2021-02-22Codechange: [SDL2] Split Start() in a few more functionsPatric Stout
This makes it a bit easier to follow what is going on, and allow future subdrivers to hook into a few of these functions. Reworked the code slighly while at it, to return early where possible.
