@Tomaž, *

Looks good, but are we immediately imposing technical debt with 

http://cgit.freedesktop.org/libreoffice/core/commit/?id=3fdc41af6370a53f7db4e52104cfd3328ee40563

by keeping the pre-Windows 8 DirectWrite2D enumeration/syntax? [1]

At this point having pulled the plug on XP and Vista, should we push forward at
6.0 and instead set the minimum supported Windows OS to 7 SP1 with "Platform
update (MS KB2670838)" [2] applied and supporting use of the "new" DWRITE
enumeration/syntax and DirectX 11.1? [3].

Guess we have to keep the old enumeration/syntax for 5.4, and backport to 5.3,
but would this help for eventualy moving rendering away from GDI, and also for
refining OpenGL rendering?
