From Martin:
Alright... I corrected SDL_SYS_ToDirection in SDL_syshaptic.c in the linux
directory of haptic. Now in all 3 cases the same value is returned, at least.
Therefore now it should behave the same way as on Windows.
I added some comments and corrected the cases SDL_HAPTIC_CARTESIAN and
SDL_HAPTIC_SPHERICAL.
I fixed a bug in the "SDL_DestroyRenderer()" function in the pandora x11 renderer (in fact the bug was in the "X11_GLES_MakeCurrent()" function) that was causing a crash when exiting SDL.
There was a problem while terminating the x11 egl window, that was preventing to quit/close SDL/SDL-window then reload SDL/SDL-window inside the same application.
