SVG Export does not match sketch

## Description

When exporting a sketch as SVG from Processing 4.3 with processing.svg, the result is not what the sketch renders in Processing.

Expected Behavior

I expect the exported SVG to match what is drawn by the internal Processing graphics renderer, which is this:

Current Behavior

Instead of matching the output from the sketch, what gets exported into the SVG is this:

Steps to Reproduce

Draw the Flower of Life pattern recursively. Because the implementation details are irrelevant here (I think?), I am only giving the code for rendering (setup and draw), which is here:
```
void setup()
{
strokeWeight(4);
stroke(200, 0, 0);
noFill();
ellipseMode(RADIUS);
//size(1920, 1080);
background(0);
fullScreen();
}
```

void draw() { beginRecord(SVG, "flower_of_life_field.svg"); int R = 100; Circle c1 = new Circle(new PVector(SCREENWIDTH/2, SCREENHEIGHT/2), R); Circle c2 = new Circle(new PVector(c1.center.x + R, c1.center.y), R); Circle[] circles = new Circle[2]; circles[0] = c1; circles[1] = c2; circles = iterate(circles, 7); for (Circle c: circles) { //println("Draw ellipses at ", c.center.x, c.center.y); circle(c.center.x, c.center.y, c.r); } endRecord(); }


3. Observe what is on the screen.
4. Open the exported SVG and notice that it is different.
5. Create this bug report.

## Your Environment
<!--- Include details about your environment. -->
<!--- Thousands of people use Processing every day and may not have this issue, --> 
<!--- so this gives us clues about why you’re running into a problem. -->
* Processing version: 4.3
* Operating System and OS version: Windows 10 Pro, build 19045.4291

## Possible Causes / Solutions
<!--- Optionally, if you have a diagnosis or fix in mind, please share. -->
This could also be an issue with the SVG library that Processing uses, in which case I will take this upstream, but I thought to report it here, first.

If I had to guess, I would say this has something to do with `ellipseMode(RADIUS)`.
