HGL actually looks like EXACTLY what I need. I only need to set pixels,
which looks like just what HGL would be good at. Only problem is that I
can't find a single tutorial for HGL. Does anyone know or any, or where
I could find one?

Updating an 800x600 texture at 30fps on a somewhat modern system is
absolu
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.

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.

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:

I'm having an unusual problem with OpenGL. To be honest I probably
shouldn't be using OpenGL for this, as I'm just doing 2D and only
drawing Points, but I don't know about any other display packages, so
I'm making due. If this is a problem because of OpenGL however, then
I'll have to learn anot
