While you can set most OpenGL attributes normally, the attributes listed above must be known before SDL sets the video mode. These attributes a set and read with set_attribute and get_attribute.

val swap_buffers : unit -> unit

swap_buffers Swap OpenGL framebuffers/Update Display

val load_bmp : string -> Sdl.Video.surface

load_bmp file -> surface Loads a Windows Bitmap file and loads it into a surface suitable for use as an OpenGL texture

val set_attribute : gl_attr -> int -> unit

set_attribute attr value Sets the OpenGL attribute attr to value. The attributes you set don't take effect until after a call to set_video_mode. You should use get_attribute to check the values after a set_video_mode call.

val get_attribute : gl_attr -> int

get_attribute attr -> value Returns the value of the SDL/OpenGL attribute attr in value. This is useful after a call to set_video_mode to check whether your attributes have been set as you expected.
