Comment 18 for bug 513980

I tracked a regression down to this commit:

    Prescale image with Bitmap::Scale to improve quality.

    In OutputDevice, when sending the Bitmap to native renderer, use
    Bitmap::Scale operation to improve quality when doing sub-sampling.
    With this Bitmaps in certain Widgets will look a lot better.

    Cleanup and translate comments, and move sal_Bool to bool in outdev2.cxx"

This commit improves the quality of the rendering but also adds unnecessary rerendering of EPS figures when scrolling.
