nmlgc 944654596d [Decompilation] [th05] Curved bullets: Update function
The algorithm for gradually rotating these clockwise or counterclockwise
towards the player could have been 5 lines long. ZUN blows it up to 26

nmlgc 24b96cd9da [Reverse-engineering] [th05] Curve bullet rendering
TH04's z_super_roll_put_tiny_32x32(), which this is based on, had

nmlgc d1f3dcd620 [Maintenance] Move all features exclusive to MAIN.EXE to a main/ subdirectory
Adding op/, main/, and end/ directories does nicely cover a great
majority of the "not really further classifiable slices" implied in
d56bd45.
