; RotateMesh Example
; ------------------
 
; In this example we will demonstrate the use of the RotateMesh command.

; Unlike RotateEntity, RotateMesh actually modifies the actual mesh structure.

; So whereas using RotateEntity 0,45,0 would only rotate an entity by 45 degrees the first time it was 
; used, RotateMesh 0,45,0 will rotate the mesh every time it is used.

; This is because RotateEntity rotates an entity based on a fixed mesh structure, whereas RotateMesh
; actually modifies the mesh structure itself.
