+ Added Gra*() skeleton functions.
! Extended XbpPresSpace() class to cover next round of implementation.
; NOTE: I am not been able to find a way to execute Gra*()
functions on a widget's presentation ( device context )
space. Qt documentation clearly indicates that this is
only possible from withing method QEvent::Paint of
concerned widget. And it is correct. Windows itself also
does not allow to paint from outside of WM_PAINT message.
However my experiments have led me to the conclusion that
this is possible if every widget is subclasses and QEvent_Paint
is method is implemented. This is a very tedious and
very error prone job. If anybody come across some sparkling
idea how this can be achieved in a resonable way, please
speak out.
However on other devices, such as, printer and bitmaps these
functions will be working. In the first phase I will implement
it for printing only, later for widgets.
