DirectWrite seems to be a poor renderer

[GoogleCodeExporter]

Which program triggers the problem? Specify the filename if possible.
All native Windows 7 programs, e.g. Explorer.

What steps will reproduce the problem?
1. Set gdipp DirectWrite renderer
2. Start Explorer
3.

What is the expected output? What do you see instead?
(1) I expect glitch-free font smoothing, but observe serious deficiencies 
instead. Numbers (dates, disk sizes, etc.) are not rendered properly at all.

(2) Accelerator underscores beneath individual characters on the menu are 
extended to underline the entire word instead.

See attached bitmap.

What version of gdipp (including renderer)? On which operating system?
gdipp 0.9.1
Windows 7 x64

Please provide any additional information below. Screenshots always help.

Sorry. I guess only few people try the DirectWrite renders and fewer report 
bugs back. So I admit the DirectWrite renders are not glitch-free for now.

I believe the glitch is DirectWrite only, correct?

Yes - it appears so. The FreeType renderer is fine.
