Disassembly of the adobe svg plugin

[Mike Hearn]

Well, I have about 2 hours now when I can work on trying to get the
adobe svg plugin to work in Wine. I have a deadline to meet for Friday
that requires the plugin, so if I can't get it working back to Windows
it is (it's like a damn magnet).

I've already located a mouse bug (problem with my last patch, oops) and
fixed it (patch sent), but the lack of render on paint problem still
eludes me. Having not got a response to the last email, I'll assume it's
OK to try poking about inside the plugin itself to figure out what's
going wrong. If anybody has some tips, now would be the time to tell me
about them :)

I hope this doesn't invalidate any patches I might produce.....

Hmm?

There's already a native plugin for Linux..

Unfortunately the Mozilla plugin does not work - the Mozilla team pulled
the XPCOM plugin interface it used, and Adobe never updated it. That's
probably because only IE offers sufficiently advanced interfaces to
perform host scripting merge, ie where the javascript environment of the
web page is merged with the javascript in the SVG file: this is a
feature we use a lot of.

Or what, did you think I ran IE on Linux for the joy of it? ;)

By the way, the link to IDA on the tools page is broken, IDA seems to
have commercialised.

Yeah, I just remembered. The guy from Adobe complained about the XPCom crap in
a private email to me back then.

I don't know. Wine graphics with explorer is slow and very annoying (just look
at a flash plugin running inside Explorer )..

IIRC, there are some specific laws allowing rev-eng for interoperability 
in the EU. Which country are you in?

The UK.

I'm not au fait with the reverse engineering laws here, and I'm not very
good at it anyway, so I'd rather avoid it if possible. But once you've
seemingly exhausted a trace what do you do next? I can't breakpoint on a
call, because the call that would let me get the right part is never
called...

You can put a software breakpoint in the code (inside a complex if 
statement if need be)
DbgBreakPoint() is the function to call.
