Added WSERV event handler to eglbringuptest This change adds an active object which listens for WSERV events on the application view window. A pointer event causes the application to be terminated. This change means that the timer which was previously used to end execution after a preset duration has been removed.

/**
RDirectGdiImageTarget is a handle to a DirectGDI adaptation-specific resource which 
abstracts the image-based rendering target. The main intention in creating this resource 
is to allow a global sharable image resource (RSgImage) to be used as a target of 
DirectGDI rendering. For example, in a DirectGDI adaptation where OpenVG is used to 
implement DirectGDI functionality, the creation of RDirectGdiImageTarget may be associated 
with the creation of an underlying EGL surface from the given RSgImage. This handle class 
and its DirectGDI adaptation-specific resource are non-sharable and local within the 
creating thread.

This class is part of a generic layer and will forward any request to the CDirectGdiDriver
singleton for the calling thread.

CDirectGdiContext is activated on an RDirectGdiImageTarget. This causes all subsequent
context drawing operations to to draw to the image resource referred to by the 
RDirectGdiImageTarget.
