5e1531944c Fixed bug 4367 - compatibility version decreased between 2.0.8 and 2.0.9
Joshua Root

The change resulting from Bug 4208 changed the compatibility_version of libSDL2 from 9.0.0 to 1.0.0. This is simply wrong.

This means that programs linked against 2.0.9 are considered by the dynamic linker to be compatible with all previous versions of libSDL2. This is not the case since new public symbols have been added.

The way compatibility_version and current_version are meant to work is:
 * current_version increases every time the library changes in any way.
 * compatibility_version is increased to match current_version whenever new public symbols are added.

Thus both versions should only ever increase. The solution to the Xcode project and autotools not having matching versions should have been to increase the version(s) in the Xcode project.

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().
