[Haskell-beginners] texture mapping with SDL

Hi everyone, I am trying to make a basic raycaster (something like the first wolfenstein 3D) using haskell and SDL 1.2 So far I have it working using coloured lines and I would like to know if there is any way to apply transforms to textures loaded in memory using SDL, in order to achieve basic texture mapping on the walls. I looked at the SDL doc but I didn't find anything looking like what I need. The code is there: https://github.com/eniac314/maze-generator/blob/master/raycaster.hs (the last part is not done yet but has nothing to do with the raycaster) I would appreciate any suggestion :)
