LOK: tile rendering regression fix

Calc fast rendering requires us to offset
the are being rendered and shift all
bitmaps accordingly. This however is
breaking Impress rendering since the
offseting logic is common (in svx and vcl).

This adds new API to enable or disable
this local rendering (as opposed to
rendering a full document as was previously
done.

The new flag is then set by Calc to
enable the offseting logic in isolation
without affecting other applications.

In one case isolation was achieved by
checking the MapModeUnit.
