Unix Notes

* Fixed potential memory corruption due to assembly bug with SDL_revcpy()
* Fixed crashes trying to detect SSE features on x86_64 architecture.
* Fixed assembly for GCC optimized 50% alpha blending blits.
* Added configure option --enable-screensaver, to allow enabling the screensaver by default.
* Use XResetScreenSaver() instead of disabling screensaver entirely.
* Removed the maximum window size limitation on X11.
* Fixed SDL_GL_SWAP_CONTROL on X11.
* Fixed setting the X11 window input hint.
* Fixed distorted X11 window icon for some visuals.
* Fixed detecting X11 libraries for dynamic loading on 64-bit Linux.
* SDL_GL_GetAttribute(SDL_GL_SWAP_CONTROL) returns the correct value with GLX_SGI_swap_control.
* Added SDL_VIDEO_FULLSCREEN_DISPLAY as a preferred synonym for SDL_VIDEO_FULLSCREEN_HEAD on X11.
* The SDL_VIDEO_FULLSCREEN_DISPLAY environment variable can be set to 0 to place fullscreen SDL windows on the first Xinerama screen.
* Added the SDL_VIDEO_FBCON_ROTATION environment variable to control output orientation on the framebuffer console.
