sc lok: Implement hi-dpi and zoom for spreadsheets.
A bit different approach than trying to paint different zoom levels at
the samet time, because it is terribly hard to achieve with Calc -
things misalign, because Calc tries to fit the lines into the pixels
etc.
Instead, always paint the spreadsheet at 100%, but use cairo to scale the
actual painting.
