There other possibilities to deal with raster graphics:

- Output the data in some image format (if you want to do it yourself,
the most simple is PPM)
- Use X11 directly (if you're on

Yeah, using openGL Points to draw 2D images will probably be pretty slow.
However, if you don't need to change your points every frame, a display list
might improve the speed quite a bit (you could still transform the points as
a whole).
Also, you could try the SDL bindings for haskell:
If you still want to use glVertex with GL_POINTS, instead of a display
list, you'd better go with vertex array or VBO.
But still, if the implicit coordinates of a raster is assumed, pairing
the coordinates with their value is overkill.

Yep, no surprise there. I would suggest using bitmap[1] to construct
your bitmap, and bitmap-opengl to put it into an OpenGL texture and
draw it on a textured quad. I think OpenGL is actually an OK choice
for this application, because it is the most portable graphics method
we have available.
