DirectWrite autocompletion

[Neil Hodgson]

On Win32, autocompletion can now use DirectWrite. This will produce better quality text drawing that matches document text more closely. 

It occurs automatically when DirectWrite is used for the main window.

Win32 autocompletion lists are now always wide enough to accommodate all list items as each is measured. Previously only the item with the most characters was measured which could lead to some items being truncated. Performance of this seems OK but there may need to be some limit for very long lists like only measuring the first 10,000 items.
