-// Description:
-// This file is part of manual test (group\inc113743.mmp) to check Wserv behaviour when
-// exposing a transparent window that is obscured by some opaque child window above it.
-// Without the fix, that transparent window will be drawn as opaque window
-// because its transparent regions is null (not re-created due to its update flag is not
-// set as it is not traceable via transparent regions linked list of windows above it.
-// Some illustration when the situation will trigger the defect (side view),
-// ----       Child (opaque)
-// ---------- Parent (transparent)
-// ----       Other transparent window obscured by opaque child
-// This defect is only reproducable when window shadowing is not used, so it cannot be 
-// tested from standard Wserv test framework.
-// @SYMTestCaseID		GRAPHICS-WSERV-0450
-// @SYMDEF  			INC113743
-// @SYMTestCaseDesc    Perform test on Wserv behaviour in exposing transparent windows which is obscured indirectly by opaque child window
-// @SYMTestPriority    High
-// @SYMTestStatus      Implemented
-// @SYMTestActions     Create opaque and transparent windows in the following dimension and z-order
-// ----       opaque child
-// ---------- transparent parent
-// ----       other transparent underneath obscured and non traceable via transparent parent iTransparentRegions
-// and then make transparent parent window invisible
-// @SYMTestExpectedResults The expected result are: other transparent window underneath is exposed and redrawn properly not becoming opaque
-//
