forked from: Old Skool [Optimised]

Old school demo effects [Optimised]
Did some optimisation there,
Fast integer maths gained around 30% cpu,
Vector calls with uint casting then gained around 50% cpu,
enabling the jump from 128 to 256 resolution in 60fps easily (ok, on my little mac)
update: more optimisation enabling to jump from 256 to 512 resolution @~60fps with fast math integer (again) instead of using _xres
update: uint casting now done with >>0
ensured stable @60 fps with pixel snapping off.
Added around 40 more "magic" equations
Click on stage to loop through them
replaced image by two sprites one with cartesian geometry and the other with polar geometry
thx @devon_o
