Added a gamefix that should fix the messed up camera views in Gundam games like "Mobile Suit Gundam Seed Destiny: Rengou vs. ZAFT II Plus" and the other ones that had this problem.

No need to set roundmode to nearest anymore, just use the gamefix.

also i think i also have to add this fix to iFPUD.cpp stuff, i'll do it tomorrow.

btw, this fix is untested because i don't have the time today to test it w/o working saved states.
