test case

Last yuv commit https://hg.libsdl.org/SDL/rev/cf166abbde4a makes yuv conversion very very fast!

bug when trying with BGR format, it produces a red image.

For instance: 
PIXELFORMAT_YV12 to SDL_PIXELFORMAT_BGR888
or
PIXELFORMAT_YV12 to SDL_PIXELFORMAT_ABGR8888

(but maybe any yuv format)

Here's a testcase. 
Sorry, no patch provided as there is too much code to dig into
