Rename some variables to match Daedulus's naming
[~] Clean up some of our sprite2d functions by using std:swap instead of a more lengthy if statement
[~] Whooopies, stupidly was setting a allocation when it wasn't required
Merge our two seperated clear and set geometry functions for GBI1 - Taken from Daedulus
[+] Properly clear the depth framebuffer, this allows the sun flare effect in Zelda, fixes DK64's jumpy camera among other things - Thanks to Salvy and the DaedulusX64 team
