Numerous SDL updates:

[*] Made stretchers and filters use a common interface
[+] Filters can now be changed at runtime using CTRL+G
[*] Replaced Simple?x filters by the ASM optimized stretchers
[-] Removed YUV output
[-] Finished removing the remove-intro feature
[!] Fixed a bit the OpenGL code. Still a lot more to do.
[*] Code cleanup

Thanks to bgKu for contributing and Linux testing of this.
