#3 Floor rendering is worse in high-detail mode than it is in low-detail

[Alexandre-Xavier]

The floor drawing algorithm used in high-detail mode seems to be the inaccurate one used in the original Doom and Chocolate-Doom. In low-detail mode, the floor is drawn more accurately with less loss of precision.

If I'm not mistaken, the released Doom source code has a different and better algorithm than the one found in the original Doom.
