FF7: Fix Widescreen glitches for Bahamut Zero and Pollensalta

[tangtang95]

Summary

Fix widescreen glitches (related to #474) for:

• Bahamut Zero stars background positioning and size
• Pollensalta cold breath attack: moving background and moving white dots

Regarding Pollensalta fix for the moving background size: this only works when in 30/60fps mode because I used a function hooked only when in 60 fps mode. I don't think there is other way to do it, but I think the correct solution should be to fix the texture page which I suppose it is inside files with .s as extension (in this case, special/hubuki/kemu.s). So I left the solution for 30/60fps just as a temporary fix.

Motivation

I don't know why either

ACKs

• I did test my code on FF7
