TextEditor: Simplify the overlay selection path

Browse Source 
The algorithm that creates the overlay selection path adds many
redundant curve elements. That is quite ineffecient when painting and it
also creates visual gaps.

This patch simplifies the path and therefore substantially reduces the
elements and removes the gaps.
