Start of intamin track, move classForTrackStyle into NL loader
Start moving TrackMesh2 to its own file
Use new model.trackStyle when instantiating LW.track
Enable camera controls on double click, or ideally right click

Currently chrome doesn't seem to want you to use right click
Include p0 and p3 in bank angle interpolation, return relative flag
Leave nltrack bank values in radians
Convert nl segment type indexes to lw style in nl loader
Use a single matrix in TrackMesh so we can store it later, fix some loops by supporting relative roll!
Oops, forgot a variable
Move LW.getMatrixAtPoint into utils to make it available everywhere, use matrices in railStep
Keyboard controls work regardless of pointerlock, dragging moves camera for browsers that don't have pointerlock
