 TODOs:
 Problems with TDSky and PicBack in Windows.
-Use RandomEngine for random number generation.
 Add MultPo's.
 Test classic mode, difficulty adjustments. Merge code for Windows.
 P.S.: Level 1 may be too hard now.

 always love to use).
 This indicates all "normal" levels are completed.
 Multiplier system was fully adopted into BLR.
-Implement a RandomEngine, replacing all rand()(Still in process).
+Implement a RandomEngine, replacing all rand().
 Fixed: Trypophobia stops if too many CLR's are used.
 Fixed the problem in All2pnt().
+Fixed blinking target.
 Make Laser::GetDist() private to avoid misusage.
 Remove unused statements:
 DWORD ColTrans(DWORD,DWORD,DWORD): replaced by
