opengl only mode

Seems that BWindow based framebuffer implementation in SDL are buggy with 3D graphics in Haiku (a BeOS clone).

explaining:

After build several games and demos with SDL that uses a minimal 3d functions, appears a small black window on the left top in the screen.

Firstly I was thinking that was a problem with vesa driver. So, I dropped my Radeon HD and use haiku with onboard nvidia (rudolf nvidia driver). Same problem.

After, I search for some opengl demos, then I found good ones in  http://nehe.gamedev.net

later, building 3d examples linking only with lGL, lGLU and lglut runs fine, leading me to think that haiku opengl and bdirectwindow are ok.

So, I started to build the same examples with SDL. This is the good one  http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=05 (on the bottom of this page have linux and linux SDL)

see this 3 screenshots. The first are only with opengl, the later ones with SDL.

the same problem I faced with this following games * Neverball * DreamChess? * FS2 * Carworld

and many others that requires opengl and SDL to do the 3d stuff
