0ea9cabb50 Don't close already-closed audio devices during SDL_Quit(). 
Otherwise, we spam a bunch of unnecessary SDL_SetError() calls.

Fixes Bugzilla #1791.

7ff764a482 Fixed the logical size for rendering to texture, thanks to Mason Wheeler. 
Mason Wheeler

The SDL_RenderGetLogicalSize function should always return the amount of pixels that are currently available for rendering to.  But after updating to the latest SDL2, I started getting crashes because it was returning (0,0) as the logical size!  After a bit of debugging, I tracked it down to the following code in SDL_SetRenderTarget:

    if (texture) {
        renderer->viewport.x = 0;
        renderer->viewport.y = 0;
        renderer->viewport.w = texture->w;
        renderer->viewport.h = texture->h;
        renderer->scale.x = 1.0f;
        renderer->scale.y = 1.0f;
        renderer->logical_w = 0;
        renderer->logical_h = 0;
    }

This is obviously wrong; 0 is never the correct value for a valid renderer.  Those last two lines should read:

        renderer->logical_w = texture->w;
        renderer->logical_h = texture->h;

563185f19c Only check for keyboard focus if the video subsystem was initialized. 
Check the hint at initialization time, as an optimization.  This isn't something we expect the application to change at runtime, and if it is we should add an API for it.

66328f31b9 Removing old dangerous signal catching code. 
* None of the supported platforms are hosed if the program crashes without cleaning up the graphics display connection.
* It's very likely to be unsafe to call SDL_Quit() at an arbitrary point from an arbitrary thread.
* Catching signals can prevent applications from getting correct stack traces from crashes.

78a7a1b54e Not using SDLmain on Windows is just fine, don't fail the initialization if the program implements WinMain() and then doesn't call SDL_SetMainReady(). 
This broke Steam's Big Picture game controller support.

I also added some more documentation so people know why main() is overridden on various platforms.

a8055a9808 Fixed bug: SDL2 Xinput joystick axis jumps from positive to negative 
Franz Schrober

Attached is my patch. It ensures that the values are correctly limitted between -32767 and 32767 (otherwise the negator - and the conversion to sint16 would corrupt the result)

I am using Motioninjoy (Dualshock 3 Sixaxxis controller on Windows 7)  together with a recent SDL2 (post rc1) and noticed with the testjoystick binary that the axis 3 (left analog up/down) jumps when going in down direction from 32257 to -32768. This seems obviously wrong and I have never seen this before. In my games the people are now going backwards before they start to sprint forward when the player actually wants to run as fast as possible backwards. This also happens on the axis 2 (right analog stick up/down)

This problem doesn't happen in DX mode

86e40a29d3 Fixed bug 1929 - SDL_Texture* from SDL_CreateTexture() causes GL_BindTexture() to segfault 
Charles Huber

If SDL_CreateTexture() takes the !IsSupportedFormat() path it will return a SDL_Texture* with a NULL driverdata member.

If you then SDL_GL_BindTexture() this will cause a segfault in GL_BindTexture() when it unconditionally dereferences driverdata.

    Sint32 delta, step;

    /* Compute difference and new sample value */
    step = step_table[state->index];
    // Some Code
}

Here step_table array have the state->index, which might be negative, so it is unsafe to assign this index to step_table array directly.
There would be a check before that to confirm its value.

9293678409 Fixed bug 1916 - SDL_Keysym contains a deprecated field for unicode which may be removed. 
Philipp Wiesemann

SDL_Keysym contains a deprecated field for unicode which may be removed for SDL 2.0 release.

As far as I can tell the field is not set on all "major" platforms and therefore will not be useful for most users. Its existence in a public header therefore becomes (in my opinion) only confusing.

f26e1bc175 Fixed bug 1897 - CPU spike on Windows with WM_EVENT and OpenGL 
buckyballreaction

On some Windows systems, when switching from fullscreen to windowed mode in my game, the CPU will spike and the application never shows the window again.

See the part of the e-mail thread here:

http://lists.libsdl.org/pipermail/sdl-libsdl.org/2013-June/088626.html

I change the window by calling:

SDL_SetWindowFullscreen(gScreenInfo.sdlWindow, SDL_FALSE);
SDL_SetWindowSize(gScreenInfo.sdlWindow, sdlWindowWidth, sdlWindowHeight);

which you can see in our source:

https://code.google.com/p/bitfighter/source/browse/zap/VideoSystem.cpp#377

Then all of a sudden the application gets stuck in WIN_PumpEvents() in SDL_windowsevents.c.  I turned on WMMSG_DEBUG and found that there was an endless stream of WM_EVENT messages.  I also found that where WM_PAINT is being handled in the callback WIN_WindowProc(), ValidateRect is somehow not clearing, or it is persisting, the WM_EVENT message like it's supposed to (according to the docs).

This may be a hardware issue.  The issue has appeared on three different systems, one of them sporadically:
 - Windows XP SP3 running in VMware 9.0 (without VMWare 3D acceleration, but with the tools and drivers installed), Host: openSUSE 12.3 x86_64, NVidia NVS 3100M
 - Windows XP SP3 64bit running in VirtualBox, Host: Debian Wheezy (stable), Mobility Radeon HD 4100 (this was the sporadic one)
 - Windows 7 64 bit, Radeon 6770
