Provide a way for ns
IProcess to launch an application on Windows without it being visible
59 bytes, text/x-review-board-request
This is needed for both bug 1359326 and bug 1364673. In both cases we either have a console window that pops up (when the application is built as a console application) or the mouse throbber that appears (if it's a GUI application). I've tried multiple workarounds in the application themselves to avoid this but couldn't find a satisfying solution. I've thought for a while about the best way to expose this. I didn't want to add another parameter to run()/runw()/runAsync()/runwAsync() because that would require adjusting a dozen C++ call sites and the same applies to adding a parameter to init(). I also didn't want to add an attribute because it made no sense to flip it after the application was launched. So I've settled on adding a new initialization method initHidden() that sets the appropriate state; I hope it's a good enough solution.

I can think of two ways to do this more extensibly: init(nsIFile executable, [optional] unsigned int flags) OR process.startHidden = true process.init(file)

OK, thanks, I'll go for the latter then because the former would require changing quite a few unrelated C++ call sites.

But this is fine. I tried that but there doesn't seem to be a way to provide a default parameter to the C++ interface, so the argument isn't really optional in C++. Anyway, thanks for the review!
