Joe Wilm 30bee80a69 Refactor cell selection out of renderer ... The terminal now has a `renderable_cells()` function that returns a `RenderableCellIter` iterator. This allows reuse of the cell selection code by multiple renderers, makes it testable, and makes it independently optimizable. The render API now takes an `Iterator<Item=IndexedCell>` to support both the new renderable cells iterator and the `render_string()` method which generates its own iterator. The `vim_large_window_scoll` ref test was added here because it provides a nice large and busy grid to benchmark the cell selection with.		2016-12-11 20:23:41 -08:00
