afd1b3dae4 Fix invalid memory access and optimise Blit_3or4_to_3or4__*
Fix invalid write at last pixel of the surface:
  when surface has no padding (pitch == w * bpp) and bpp is 3
  with Blit, no colorkey, and NO_ALPHA same or inverse rgb triplet

Optimise by using int32 access:

670f3d3327 Fixed bug 4484 - use SIMD aligned memory for SDL_Surface
Surfaces are allocated using SDL_SIMDAlloc()
They are marked with SDL_SIMD_ALIGNED flag to appropriatly free them with SDL_SIMDFree()
(Flag is cleared when pixels is free'd in RLE, in case user would hijack the pixels ptr)

When providing its own memory pointer (SDL_CreateRGBSurfaceFrom()) and clearing
SDL_PREALLOC  to delegate to SDL the memory free, it's the responsability of the user
to add SDL_SIMD_ALIGNED or not, whether the pointer has been allocated with SDL_malloc() or
SDL_SIMDAlloc().

6d89a7bc71 Emscripten: remove GLES_DeleteContext implementation
It was calling glClear without a context. The issue it was trying to
solve was actually that after destroying a window and creating a new one
, the contents of the old window were preserved. This no longer happens
since we resize the window to nothing on destroy.

e5f8801f55 Android: prevent concurrency in Android_SetScreenResolution() when exiting

- SDLThread: user application is exiting:

- ActivityThread is changing orientation/size
    surfaceChanged() > Android_SetScreenResolution() > SDL_GetVideoDevice()

- Separate function into Android_SetScreenResolution() and Android_SendResize(),

dc263450ff Android: create Pause/ResumeSem semaphore at higher level than CreateWindow()
- If you call onPause() before CreateWindow(), SDLThread will run in infinite loop in background.

- If you call onPause() between a DestroyWindow() and a new CreateWindow(), semaphores are invalids.

SDLActivity.java: the first resume() starts the SDLThread, don't call
nativeResume() as it would post ResumeSem. And the first pause would
automatically be resumed.

1803944bb2 Android: concurrency issue for Android_SetWindowFullscreen()
It accesses data->native_window, which can be changed by onNativeSurfacedChanged().

Currently, Android_SetWindowFullscreen() may access data->native_window after it
has been released, and before a new reference is acquired.

(can be reproduced by adding some SDL_Delay() in onNativeSurfacedChanged and
Android_SetWindowFullscreen() ).

35722b6423 Android: fix wrong state after immediate sequence pause() / resume() / pause()
It may happen to have the sequence pause()/resume()/pause(), before polling
any events.

Before, it ends in 'resumed' state because as the check is greedy.
Now, always increase the Pause semaphore, and stop at each pause.
It ends in 'paused' state.

Related to bug 3250: set up a reconfiguration of SurfaceView holder.
Turn the screen off manually before the app starts
(repro rate is not 100%..)

d4c0f498db Fixed bug 4255 - SDL_GetGlobalMouseState() returns incorrect Y on secondary display
Julian Raschke

I use an open Mac laptop with an additional external monitor. The coordinate spaces from SDL_GetGlobalMouseState() and SDL_GetWindowPosition() match on the primary display, but not on the secondary display.

Cocoa window coordinates are vertically flipped in relation to the primary display:

https://github.com/spurious/SDL-mirror/blob/release-2.0.8/src/video/cocoa/SDL_cocoawindow.m#L219-L222

However, Cocoa_GetGlobalMouseState inverts the cursor Y coordinate per-display:

https://github.com/spurious/SDL-mirror/blob/release-2.0.8/src/video/cocoa/SDL_cocoamouse.m#L320-L323

Suggested fix: Replace the for-loop with this simpler calculation:

    *x = (int) cocoaLocation.x;
    *y = (int) (CGDisplayPixelsHigh(kCGDirectMainDisplay) - cocoaLocation.y);

2a885eb036 Android: fixed immediate transition to pause and resume.
"Pause" transition will add events:
 SDL_WINDOWEVENT_ENTER
 SDL_WINDOWEVENT_FOCUS_LOST
 SDL_WINDOWEVENT_MINIMIZED
 SDL_APP_WILL ENTER BACKGROUND
 SDL_APP_DID ENTER BACKGROUND

"Resume" transition will add events:
 SDL_APP_WILL ENTER FOREGROUND
 SDL_APP_DID ENTER FOREGROUND
 SDL_WINDOWEVENT_FOCUS_GAINED
 SDL_WINDOWEVENT_RESTORED

If Android application doesn't empty the event loop in between, it enters in
"paused" state when SDL_WINDOWEVENT_RESTORED is fetched.

See bug 3250 for pratical case.

ca184ac386 Android: concurrency issue with egl_surface EGL_BAD_SURFACE - (bug 4142)
Occurs when application goes to background:
- Java activity is destroying SurfaceView holder and "egl_surface" (in onNativeSurfaceDestroyed())
- While native thread is in Android_GLES_SwapWindow(), prepared to call SDL_EGL_SwapBuffers()

The error is "call to eglSwapBuffers failed, reporting an error of EGL_BAD_SURFACE"

It an be reproduced easily by adding a SDL_Delay(100) at the begining of SDL_EGL_SwapBuffers(),
and putting the application into background.
