I am about to deal with the issue of clipping in the program I am working on, and would like some advice on how to go about it. I have been told that by using the Layers Library functions I can do this, but my reading has neither confirmed nor denied this. By clipping I mean that I would like to be able to pass the drawing functions lines whose endpoints may not be within the screen boundaries without drawing into unintended memory. If the Layers Library can be used to do this could someone please enlighten me? Assuming this can be done, some information as to how the L.L. goes about it would be appreciated so I can compare them to custom routines I could write. Also, I am in need of a Fixed point math library, and before I re-invent the wheel I thought I'd ask and see if anyone knows of such a beast? I work in Modula-2, so M2 would be best???
