Render tiles from calc.
Currently the document size and number of cells to be rendered is hardcoded, this will need some more work to select the correct cells for a given tile (i.e. cells from location). Also, there isn't really a "size" for a calc sheet, so presumably we'd need to instead return the area containing cells that aren't empty, whilst still being able to render larger tiles? (And in any case the client will need to be aware of this and provide an appropriate interface, i.e. the current LO UI simply extends the sheet ad-infinitum.) We also currently get some warnings most likely related to the way we push our OutputDevice into the rendering methods: SdrPageView::DrawLayer: Creating temporary SdrPageWindow (ObjectContact), \ this should never be needed Change-Id: Ia9d64d7de6c22d5b401350f88497a7ec106f1973
