[Mono-list] Mono and Automation tools

[Jonathan Pobst]

Currently, the way Winforms is written, there is no way to change the 
ClassName.  The name that gets used (on Windows) is:

string.Format ("Mono.WinForms.{0}.{1}", 
System.Threading.Thread.GetDomainID ().ToString (), classStyle);

where classStyle is the CreateParams.ClassStyle.

The benefit of this is that we only register a few classes with Windows, 
and reuse them quite heavily.  The downside I guess is that you can't 
set your own ClassName.

We could probably make a change so that if a ClassName is given, we 
could append it to the current naming scheme.  However, we probably 
wouldn't put class names in our controls (you would have to override the 
CreateParams in each of your controls and put a class name in).

We should be branching for 1.2.5 this week, so I don't feel comfortable 
making such a change for 1.2.5, but I could change it after that if it 
helps any.
