[SDL] Make window stay on top

[cron at odi.com.br]

Hello,

I'm trying to make a SDL panel to use with wxWigets to play video, right 
now the sdl_furface is going along with the wxPanel keeping the same 
size and the same left and top coordinates, however the sdl_surface  
(using YUV overlay) stays behind the wxPanel, so i ask:

Is there a way to make a sdl_surface stay on top of others windows?
