fa8c83c1c1 Remove almost all instances of "volatile" keyword. 
As Tiffany pointed out in Bugzilla, volatile is not useful for thread safety:

https://software.intel.com/en-us/blogs/2007/11/30/volatile-almost-useless-for-multi-threaded-programming/

Some of these volatiles didn't need to be, some were otherwise protected by
spinlocks or mutexes, and some got moved over to SDL_atomic_t data, etc.

Fixes Bugzilla #3220.

b24586309c Fixed dynapi for new SDL_WarpMouseGlobal() function signature. 2015-07-18 00:04:49 -04:00

e346f14277 SDL_WarpMouseGlobal() should return non-void. 
There are platforms it isn't implemented on (and currently can't be
implemented on!), and there's currently no way for an app to know this.

This shouldn't break ABI on apps that moved to a revision between 2.0.3 and
2.0.4.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later. 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
