--- Comment #5 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Would say DirectWrite/Direct2D was implemented to support OpenGL rendering, but
not fully.

Per ESC (2017-05-24) for the 5.5/6.0 build we will fully drop XP and Vista
support. That decision now provides opportunity to fully refactor Windows
graphics to DirectWrite/Direct2D rendering.

Khaled completed Akash's work on HarfBuzz Common Layout (bug 89870) in 5.3 and
5.4 they've routed more of the Windows rendering through DirectWrite calls
expanding on work by Tor, Tim and Martin for Graphite support. 

But the DirectWrite/Direct2D implemented thus far was only a subset, it now
needs refinement (bug 107521). And needs support for floating point positioning
(bug 103322) to support sub-pixel rendering. While loss of grayscale mode
antialiasing with our DirectWrite implementation is causing issues for
non-OpenGL Windows users (bug 106990).

@Adolfo, you OK with closing this?
