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().

Added SDL_DROPBEGIN and SDL_DROPCOMPLETE events, plus window IDs for drops. This allows an app to know when a set of drops are coming in a grouping of some sort (for example, a user selected multiple files and dropped them all on the window with a single drag), and when that set is complete. This also adds a window ID to the drop events, so the app can determine to which window a given drop was delivered. For application-level drops (for example, you launched an app by dropping a file on its icon), the window ID will be zero.

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().
