// Description:
// Test redraw storing
// Tests Storing the Redraw command mechanism in the window server.
// The first time a window is redrawn its commands are stored. When
// the window needs to be redrawn, the stored commands will be used
// rather than issue a redraw request to the client.
// The principle behind this test is to do lots of different types of drawing to a window,
// invalidate the window and test that no redrawing occurred, instead the stored commands
// should be used to generate the content of the window.
//

						When OW2 is set invisible, you want the screen to be drawn as OW1,

	//Unfortunatly there is no direct way of disabling shadows from the test code so under normal running the 
	//following tests will never hit the defect and always pass.
	//To disable shadows the WSERV source code has to be manually altered by editing the CWsClientWindow::CommandL
	//method in clwin.cpp. In the EWsWinOpSetShadowHeight case alter the SetHeightDiff(*pData.Int); function call
	//to read SetHeightDiff(0);
	//The use cases are related to DEF096874 in that the problem occurs when we have 2 windows overlaying each other 
	//where the top window is completely tiled by child windows. DEF096874 occurs when the window that is tiled is made 
	//invisible, with the result that the windows are not redrawn correctly. 
	//The use cases reproduced by this test are when the two windows are either fully or partially obscured by a 
	//further transparent window laid over the both of them. When the tiled window is made invisible then 
	//the windows are not updated properly resulting in either transparency problems or the windows not being drawn 
	//correctly. 
	//There are further use cases not addressed here i.e. tiled windows becoming visible underneath a transparent window
	//that relate to the same fundamental problem but are correctlly addressed by the defect fix.
