Before we get this far, the Windows front end has a series bug
just selecting fonts and rendering text. This is why there is no binary
AbiWord-2.0 release. We could *really* use some experienced Windows
developer time to resolve it and fix it so we can release AbiWord-2.0.1
with a non-broken Windows binary. I'm sure the fix is less than 50 LOC
(prolly more like 20) BUT it needs someone who understands how the
Windows GDI actually works.
Please read the threads related to
It is rather frustrating to read that "basic graphic classes that could
easily be extended to support the few missing pieces (curves, etc.)."
When this basic stuff is broken and the simple little extensions (that
are trivial in GTK2) will take ages to implement on Windows.

No We just blit images onto the graphics class.
