player locator optimized and behavior made way better, but still not perfect
gluProject working in RenderEntityInfo

still need to figure out what to do when target is behind and clean up
unused commented code
use partial tick time to make it way smoother
RenderEntityInfo: everything is awesome

except maybe reversed 3rd person cam
made it work for reversed 3rd person; also removed debug text accidentally left in
convert tabs to spaces
Merge pull request #21 from kevinwchang/master
