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.

SDL on BeOS R5
==============

You can build SDL on BeOS like any other GNU style package.
e.g. ./configure && make && make install
By default it is installed in /boot/develop/tools/gnupro/{bin,lib,etc.}

Once you install SDL, you need to copy libSDL.so to /boot/home/config/lib,
so it can be found by the dynamic linker.

Enjoy!
