Quality of image in impress

[leandromartinez98]

Is it possible to improove the quality of the overall visualization in impress? For example,
when I draw a line or a sphere, they looks very aliased. The spheres,
for instance, seem to be built from several segments (the border). In other graphic programs, like inkscape, everything seems much more smooth. It is possible to
increase the quality of the overall renderization of the slides?

I'm using OOffice 3.0 and this has improved relative to the 2.4.1 version I had,
but it is not satisfactory yet. This is really preventing me from using the Impress
all the time, since my presentations rely reavilly on technical sketchs.

Here there is an example of what I'm talking about:

When I export to pdf
the aliasing gets better, but, of course, I cannot use all resources then.

Thanks,
