lok: send cell selection rectangle and cell area fill rectangle

Instead of text selection start/end for cell selection we send a
cell selection rectangle event. This is needed so we're able to
differentiate when to draw cell selection and text selection
markers.

In addition send cell fill area rectangle, which is the area where
we need to hit to trigger area fill functionality in Calc.
