0003 SGLFW_Evt.h : manage event data and corresponding OpenGL progs
0004 ===============================================================
0005
0006 HMM : Perhaps rename SGLFW_Rec.h for record
0007
0008 Started from the old SGLFW_Event.h and removed the geometry rendering,
0009 as prefer modular arrangement with geometry rendering in SGLFW_Scene.h
0010 and event rendering here.
