How can I verify this issue without changing the code that creates the canvas
for the presenter console extension?  Does the canvas, that is created for the
com.sun.star.rendering.VCLCanvas service, internally map to gdipluscanvas?

The main problem described by this issue is (was, before the workaround of
explicitly instancing VCLCanvas service) that there can only be one instance of
the DirectX canvas. When the default service is used to create a canvas for the
presenter console then this canvas can be the one DirectX canvas.  This means
that the canvas of the actual presentation is either
a) a second DirectX canvas that conflicts with the first or
b) another type of canvas that is not antialiased nor optimized with respect to
rendering speed.

Having a second antialiased and optimized canvas for the presenter console would
be very nice but is of secondary importance.

So, what I am looking for here is a canvas service that 
A) takes care of the DirectX problem (not stealing the single DirectX resource
from the fullscreen presentation),
B) is platform independent, and
C) automatically provides the best (with respect to display quality and speed)
canvas that is available on the platform.
