c59d9923b3 Implemented more flexible blending modes for accelerated renderers
This fixes bug 2594 - Propose new blend mode, SDL_BLENDMODE_BLEND_DSTA

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
	                                       SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,
	                                       SDL_BLENDOPERATION_ADD,
	                                       SDL_BLENDFACTOR_ZERO,
	                                       SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDOPERATION_ADD);

This fixes bug 2828 - Subtractive Blending

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_SRC_ALPHA,
	                                       SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDOPERATION_SUBTRACT,
	                                       SDL_BLENDFACTOR_ZERO,
	                                       SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDOPERATION_SUBTRACT);


This goes partway to fixing bug 3684 - Add support for a pre-multiplied alpha blending mode

	blendMode = SDL_ComposeCustomBlendMode(SDL_BLENDFACTOR_ONE,
	                                       SDL_BLENDFACTOR_ONE_MINUS_SRC_ALPHA,

0112f61889 Fixed bug 3743 - make testautomation_sdltest.c to compile
Ozkan Sezer

The attached patch makes testautomation_sdltest.c more compatible wrt
LLONG_{MIN|MAX} macros and makes it to compile on older systems  (e.g.
glibc-2.8) too, by replacing LLONG_{MIN|MAX} with INT64_{MIN|MAX}.

c.f.: bug , where the same issue was described for SDL_test_fuzzer.c

2da830a909 Fixed bug 3741 - more compatible initializers for arrays
Ozkan Sezer

An array defined like  int xPositions[] = {-1, 0, 1, w-1, w, w+1 };
errors with Open Watcom: it strictly wants constants.  Small patch
like below makes things more compatible.

93a520b385 Fixed bug 3605 - Software renderer no longer renders after Android screen orientation change
Sylvain

This still happens with the current trunk version.  (software renderer of testdrawchessboard.c)

When there is a rotation, the window size changed and the internal surface is marked as "surface_valid == SDL_FALSE".
And all further call fails.

SDL_video.c :

2478 void
2479 SDL_OnWindowResized(SDL_Window * window)
2480 {
2481     window->surface_valid = SDL_FALSE;
2482     SDL_SendWindowEvent(window, SDL_WINDOWEVENT_SIZE_CHANGED, window->w, window->h);
2483 }

some error set to :
2233         return SDL_SetError("Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface");


So, this seems to be the behavior of the API ...


In the loop() function of testdrawchessboard.c, we can recreate the surface/renderer :

 65        if (e.type == SDL_WINDOWEVENT)
 66        {
 67             if (e.window.event == SDL_WINDOWEVENT_SIZE_CHANGED)
 68             {
 69                surface = SDL_GetWindowSurface(window);
 70                renderer = SDL_CreateSoftwareRenderer(surface);
 71             }
 72             /* Clear the rendering surface with the specified color */
 73             SDL_SetRenderDrawColor(renderer, 0xFF, 0xFF, 0xFF, 0xFF);
 74             SDL_RenderClear(renderer);
 75        }

And it displays correctly.

658975f381 Fixed bug 3639 - SDL_GetPrefPath returns a path with two consecutive slashes on Unix if org is omitted
Fabian Greffrath

we use SDL_GetPrefPath() in Chocolate Doom to get a reasonable directory to save and restore config files and savegames:

https://github.com/chocolate-doom/chocolate-doom/blob/sdl2-branch/src/m_config.c#L2162

However, since there is no "organization" behind Chocolate Doom and there is really only one "product" called Chocolate Doom, we pass an empty string for the org parameter and the package string for app.

This leads to two consecutive slashes in the path returned by SDL_GetPrefPath() like this:

/home/user/.local/share//chocolate-doom/

While this is harmless, it sure looks bad.

I believe that it should be possible to either pass a NULL pointer for the org parameter or at least have the function detect an empty string as a means to express "there is no origanization, just a single product". The generation of the path string to be returned by the function will have to get adapted accordingly.

a52d48c5ab Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11
Mark Callow

The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile:

- Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can
  say to use the OpenGL ES driver & EGL rather than the Open GL
  driver. (For bug )
- Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum
  OpenGL ES version supported by the OpenGL driver (for bug )
- Modifies the test that determines whether to use the OpenGL
  driver or the real OpenGL ES driver to take into account the
  hint, the requested and supported ES version and whether ES 1.X
  is being requested. (For bug  & bug )
- Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds
  the test to the VisualC projects.

With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

082132a70c Fixed binding the D-pad on some Super NES style controllers
Fixed a case where partial trigger pull could be bound to another button

There is a fundamental problem not resolved by this commit:

Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on.

Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work.

My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.
