2021-02-17Fix: [SDL2] simplify what to redraw to prevent tearing (#8685)Patric Stout
When there are a lot of rects to redraw, of which one of the last ones is almost the full screen, visual tearing happens over the vertical axis. This is most visible when scrolling the map. This can be prevented by using less rects. To simplify the situation, and as solutions like OpenGL need this anyway, keep a single rect that shows the biggest size that updates everything correctly. Although this means it needs a bit more time redrawing where it is strictly seen not needed, it also means less commands have to be executed in the backend. In the end, this is a trade-off, and from experiments it seems the approach of this commit gives a better result.
2021-02-17Fix 52317bb7: [SDL2] ensure we don't try to blit out of bounds (#8684)Patric Stout
During resizing, there can still be dirty-rects ready to blit based on the old dimensions. X11 with shared memory enabled crashes if you try to do this. So, instead, if we resize, reset the dirty-rects. This is fine, as moments later we mark the whole (new) screen as dirty anyway.

2021-02-14Add: [OSX] Automatic zoom level suggestion for Cocoa video driver.Michael Lutz
2021-02-14Add: [Win32] Automatic zoom level suggestion for Win32 video driver.Michael Lutz
The zoom level suggestion is based on the DPI scaling set in Windows. We use 150% scaling as the threshold for 2X zoom and 300% scaling as the threshold for 4X zoom.

We never change the real screen resolution on OSX. As such, offering a list of resolutions is pointless. Instead of that, offer the user a list of commonly used window sizes up to the current screen size.

2021-02-11Change: [SDL2] Remove unneeded delay of redrawing the screenPatric Stout
In testing, I could find no reason why this statement is here. The comment is rather unclear (it states what it does, but not why it would be needed). This line of code was introduced with f4f40448, which gives no further insight on why it would be needed to have it here. As such, let's remove it and see if anyone else reports any problems with it. If so, this commit can be reverted and a more clear comment should be added what this line of code is dealing with (the WHY, not the WHAT).
2021-02-11Codechange: [SDL2] Don't use globals if we can do with localsPatric Stout
2021-02-11Codechange: [SDL2] Name paint function Paint(), like other drivers doPatric Stout
This reduces confusion when reading different drivers.
2021-02-11Fix 30e69c51: palette was not marked dirty when creating a newPatric Stout
This means the code depended that the caller did this for us before MakePalette() is executed, which is neither a requirement nor a promise the code makes.
2021-02-06Fix #8029: [SDL2] disable draw-thread on wayland SDL video driver (#8648)Patric Stout
When the wayland SDL video driver is used, an EGL context is created in the main thread. It is not allowed to update this context from another thread, which is exactly what our draw-thread is trying. The other solution would be to move all of SDL into the draw-thread, but that would introduce a whole scala of different problems. The wayland SDL backend is significantly faster than the X11 SDL backend, but there is a performance hit nevertheless.

2021-01-30Codechange: [SDL2] Use MakeDirty() to force a redrawPatric Stout
The original code is "strictly correct", but just reads really weird, and we use MakeDirty() in several other places instead too.
2021-01-30Codechange: [SDL2] Rework how palette is updatedPatric Stout
It now follows more what the Win32 driver does, and has far less exceptions and special casing. MakePalette creates the Palette and prepares surface. UpdatePalette updates the Palette. CheckPaletteAnim checks if UpdatePalette needs to be called and marks the whole screen dirty so DrawSurfaceToScreen will do a full redraw.
2021-01-30Fix: [SDL2] Display why SDL_CreateWindow() failed in case it doesPatric Stout
All SDL_NNN errors print SDL_GetError, except for this one place.
2021-01-30Codechange: [SDL2] Split away CreateMainWindow from CreateMainSurfacePatric Stout
This makes the code a bit more readable, as both intentions are more clear, and there is less nesting in the main function.
2021-01-30Codechange: [SDL2] reworked the different surfaces to make it more readablePatric Stout
2021-01-30Codechange: [SDL2] Only prepare "caption" if you are going to us itPatric Stout
2021-01-30Codechange: [SDL2] Minor code cleanup to remove silly variablePatric Stout
2021-01-30Codechange: [SDL2] Only set _cur_palette, never _local_palettePatric Stout
2021-01-30Codechange: [SDL2] Move FindStartupDisplay to its own functionPatric Stout
2021-01-30Codechange: [SDL2] reworked FindResolutions to be more like the restPatric Stout
There was no default resolution fallback, and the code was different from the win32 driver. It is now named the same and much more similar.
2021-01-30Codechange: [SDL2] remove include-protectionPatric Stout
This is already done by CMake: if SDL2 is not detected, this file is not included.
2021-01-17Codechange: [SDL2/Win32] Be consistent how 0bpp blitters are not allowedPatric Stout
Sometimes it returned an usererror(), sometimes Start() failed. Now it always fails on Start(), so nothing else has to check again what blitter is used. AfterBlitterChange() can never change to a 0bpp, so it is sufficient to guard this with an assert().
2021-01-17Codechange: [Win32] Use _local_palette for most operationsPatric Stout
Other drivers do this too, and this makes the world a bit more the same.
