Overlay functions are being replaced by YUV textures.
If the driver doesn't support YUV textures, they can be emulated by backing
the texture with an RGB texture and using the software conversion routines.
Note that it doesn't make sense to lock a portion of a YV12 texture, since
you'd need to return three pixel pointers and pitch values instead of the
one that's available through the API. I'm guessing that's one of the reasons
DirectX 9 doesn't support this format at all.

11 This is the Simple DirectMedia Layer, a general API that provides low |
| 0 | 12 level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, |
| 13 and 2D framebuffer across multiple platforms. | |
| 14 | |
| 1659 | 15 The current version supports Linux, Windows, Windows CE, BeOS, MacOS, |
| 16 Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. | |
| 17 The code contains support for AmigaOS, Dreamcast, Atari, AIX, OSF/Tru64, | |
| 18 RISC OS, SymbianOS, and OS/2, but these are not officially supported. | |

| 22 Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, | |
| 23 Pike, Pliant, Python, Ruby, and Smalltalk. | |

| 30 The best way to learn how to use SDL is to check out the header files in | |
| 31 the "include" subdirectory and the programs in the "test" subdirectory. | |
| 32 The header files and test programs are well commented and always up to date. | |
| 1659 | 33 More documentation is available in HTML format in "docs/index.html", and |
| 34 a documentation wiki is available online at: | |
