Title: Fix negative texel wrapping in softgpu

Answer to the comment: no, it doesn't. So it was crashing. Adding abs() helped, but I found that using floor() was faster (we're only talking 2-3% speed -> 3.6% speed, though... I guess that's 20% faster, heh, but probably only for that scene.)

No longer crashes in Jeanne d'Arc, still looks awful. Was wondering if maybe it showed the characters.

To confirm my math:
```
-0.3 - floor(-0.3)
= -0.3 - -1.0
= 0.7

0.6 - floor(0.6)
= 0.6 - 0.0
= 0.6
```
