Add support for just loading the correct dylibs about opencv-processing

[atduskgreg]

That's an interesting thought, Rune. I usually end up using both the OpenCV for Processing object as well as built-in OpenCV objects like Mat, etc. So I don't very frequently have the use case you're talking about. At the very least I'm going to be using the main OpenCV object for I/O to and from PImages, etc. No?

Yes, I guess it's more of an advanced user thing, as most people will always create a Processing object. I was just porting a Random Forest example in this repo:

https://github.com/runemadsen/random-forest-processing-opencv/blob/master/random_forest.pde

You'll see that my source code looks like this:

// we use Greg's nice little library to load the correct dylibs at runtime. We never actually 
// use this object, but we get error if we don't instantiate it before using the core OpenCV classes
OpenCV opencv;
opencv = new OpenCV(this, "test.jpg");

// now use the Mat class
Mat training_data = new Mat(200, 64, CvType.CV_32FC1);

I would consider it low priority, but wanted to ping you so you know the use case.

Yeah. I saw that. Looks great. Implementing Random Decision Forests has been on my list so thanks for getting that ball rolling! I guess what's weird about this is that you're using it without any images. Which is kinda funny in OpenCV! But I see what it would be useful. You're basically in a mode of using OpenCV's machine learning libraries for their own sake rather than with images. That's a good use case. I'll see about adding that init. But in the meantime, you can just give the OpenCV constructor width and height, you don't have to give it an image.

Yes, it is kind of weird. I guess my training data is a matrix, so it's image-like, without an image actual to load.

Ah, didn't see that constructor in the source. I'll remove the test image then. That empty constructor is basically the same as init, so I think you can close this for now.

Thanks a bunch.

Ok. Cool.
