I am working on Windows and I am planning to submit some patches
(plugin loading) but I have problem make all regression tests
(run-webkit-tests) pass without unmodified code.

I followed all the instructions:


but as it warned, I saw "metric-related failures".

And recently aroben just told me on IRC that I may still have
difference in the metrics so that I suppose that this problem has not
be resolved.

The most related posts that I could find in this list is kinda old.

However, on WebKit BuildBot I saw that Windows release and debug build
are both "green". I don't see the option "--tolerance" specified.
There must be some tricks of setting up the machine. Any clue please ?

(full result of 2 failures attached)

One thing may make he difference. In my MacBook, I found *almost all*
fonts listed in:


except "Times *.ttf". I did find "Times New Roman8.ttf" so that I
renamed the later.
