It looks like the save() functions do not work. Is there another way to save a processing screen?

Is there a way to determine the width of a textblock using an arbitrary font? 

I am trying to convert a GPL font to svg for use with processingjs. I cannot seem to get processingjs to recognize my several attempts at conversion, so hopefully someone on this thread can help convert this to svg: 

Is there a way to implement a preloader for a processing script that might take a while to run? 

In PHP and other languages, using classes / OOP features adds an extra overhead. I am wondering if this is also the case with processing.

What is the best way to find the bounding box (or bounding shape) of an arbitrary 2D shape defined by a set of coordinate points (two serialized 1-dimensional array)

Suppose you have multiple arrays, each a dimension of a coordinate set.. The max and min functions work well to find the max and min, but what if you want to find the index of the result. Is there a built-in function that retrieves the index of the find for max/min?

Suppose you arbitrarily draw a curve -- say, a random walk curve that closes in on itself (returns to a startpoint close to where it was before) -- what is the best way to find the centerpoint of the resulting "shape" formed by the closed curve. 

Looking at LoadImage examples on processingjs ported from processing  -- none of the images seem to load... Does LoadImage not work on processingjs? 

Is it possible to do numerical integration in processing? Can I find the area bounded by a particular curve drawn in processing? 

I'm trying to learn processing by converting Java algorithms to Processing.
