indexing: add LOKit API to render the search result into a bitmap

This adds a new LOKit API to render the search result into a bitmap
buffer. It combines the SearchResultLocator to get the location
inside the document of the search result (a series of rectangles)
and the existing LOKit paintTile API to render the result into
a bitmap (byte) buffer.

It also adds a LOKit test to show how the API is used and to render
a search result of a example document.
