swf-linklabels.exe sample at winforms/linklabel does not shows strings
with multiple links correctly under win32. It works fine on Linux.

At the top you can see the sample with Microsoft .net and the bottom how it looks with Mono on Win32

I'm guessing this has something to do with a difference in behavior
between our libgdi MeasureCharacterRanges and microsoft's, since it
works fine on linux and .net but not mono on windows.

The output seems ok on linux as reported, however the sample app dies
a few second after showing it's window.

I'm updating to latest SVN to try again...

The NRE isn't present using "this morning" SVN.

Using the "shouldn't be visible" focus rectangle it seems we display
some "empty" space before the text. It looks like this is our missing
space at the right end of the string (length is ok). For example look
at the red-background label, the text should start much closer to the
left than what we're displaying.

There are a few other bugs visible when running the sample (besides
the aft-mentioned focus). I have a fix for the label alignement (e.g.
center, right).

i've committed the alignment fix (using ClientRectangle instead of
layout_rect.)

going to look at MeasureCharacterRanges now.  looks like it's not
offseting the regions properly?

looks like the only remaining problem as far as this bug goes is the
word Mozilla in the last link in the UI.  the entire word shows the
link cursor, and clicking anywhere on it activates the link.  But the
focus rectangle shows the right placement/length..  so I'm thinking
this is probably in the LinkLabel code.

https://bugzilla.novell.com/show_bug.cgi?id=MONO79765 has another testcase, this one just for the actual text
layout, and not for the link pieces.
