The showrev.sh script shows the tip, instead of the current hg revision. This can be mismatched if one were to use hg update -r ??? to revert to a previous revision.
Patch uses parents instead of tip, which will show the revision that the source is compiled with, instead of the latest revision that the user who is compiling has downloaded.
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().
