5dcac4ccdf Fixed 4669 - Using the software SDL_Renderer on Android leads to GL errors & black screen when window resizes 
Sylvain

I think what happening with the software renderer is:

* you're somehow in background (so texture creation is not possible)
* it resizes and wants to push a SDL_WINDOWEVENT_SIZE_CHANGED
It call:
https://hg.libsdl.org/SDL/file/a010811d40dd/src/render/SDL_render.c#l683
* GetOutputSize
* SW_GetOutputSize
* SW_ActivateRenderer
* SDL_GetWindowSurface
* SDL_CreateWindowFramebuffer which is mapped to SDL_CreateWindowTexture
and it ends up re-creating the surface/a texture, while being in background

41c718db85 Fixed bug 4469 - make SDL_CreateTextureFromSurface pick a more appropriate format 
Sylvain

Currently SDL_CreateTextureFromSurface picks first valid format, and do a conversion.

    format = renderer->info.texture_formats[0];
    for (i = 0; i < renderer->info.num_texture_formats; ++i) {
        if (!SDL_ISPIXELFORMAT_FOURCC(renderer->info.texture_formats[i]) &&
            SDL_ISPIXELFORMAT_ALPHA(renderer->info.texture_formats[i]) == needAlpha) {
            format = renderer->info.texture_formats[i];
            break;

It could try to find a better format, for instance :

 if SDL_Surface has no Amask, but a colorkey :
   if surface fmt is RGB888, try to pick ARGB8888 renderer fmt
   if surface fmt is BGR888, try to pick ABGR8888 renderer fmt
 else
   try to pick the same renderer format as surface fmt

if no format has been picked, use the fallback.


I think it goes with bug 4290 fastpath BlitNtoN
when you expand a surface with pixel format of size 24 to 32, there is a fast path possible.


So with this issue:

- if you have a surface with colorkey (RGB or BGR, not palette), it takes a renderer format where the conversion is faster.
  (it avoids, if possible, RGB -> ABGR which means switching RGB to BGR)

- if you have a surface ABGR format, it try to take the ABGR from the renderer.
  (it avoids, if possible, ABGR -> ARGB, which means switch RGB to BGR)

2ee9b1ddce Fixed bug 4025 - SDL_Renderer OpenGL : add support for textures ABGR, RGB, BGR 
Sylvain

OpenGLES2 SDL renderer has support for textures ARGB, ABGR, RGB and BGR, whereas OpenGL SDL renderer only had ARGB.

If you think it's worth adding it, here's a patch. I quickly tried and it worked, but there may be missing things or corner case.
