[Since FP re-write] Some sloped 3D floors don't render

[AFADoomer]

Since the floating point re-write, I've had some issues with sloped 3D-floor rendering... I have multiple sectors with the exact same tags, but seemingly random sectors (the same ones every time) will not display the 3D floors (but only from certain sides). These sectors used to render properly in GZDoom, and still do in GZDoomBuilder (and I haven't edited in months, so nothing in the map changed), so I'm not sure what is different (maybe a map error that was previously hidden?). I've even re-created the 3D floors and re-tagged everything in a different version of the map, to no avail.

You can see an example of this here:

MAP01
warp -190 0 120

(No textures in the .wad, but you can still see the issue - the wall in front of the player is supposed to be solid, not have angled chunks missing)

fixed. This was caused by precision issues when calculating the sector's center. The old algorithm was only working with fixed point precision.

Confirmed fixed on my end. Thanks!
