Draws a stretched bitmap with or without a mask.

@param aSrcMode is the source display mode
@param aDstMode is the destination display mode
@param aSession is the windows server session
@param aWindow is a reference to the window
@param aGc is the graphics context of the window
@param aNumIterations is the number of iterations to run the test
