GSoC: Enable building Harfbuzz with Graphite
Harfbuzz will now need to be built with Graphite support. This allows
Harfbuzz to handle Graphite fonts. In case we all building with
system Harfbuzz, then it should be built with Graphite support else
we error out.

GSoC: Remove DrawServerFontLayout and add DrawSalLayout
DrawServerFontLayout is removed. A more generic function DrawSalLayout
with two different signatures is added. This allows the appropriate
function to be used depending on the platform.
