loadShape() problems with SVGs that have . starting a number in a path

Created by: benfry

Re-saving the SVG in 1.0 format with Illustrator instead of 1.1 will fix the issue, but the problem seems to be that a leading . in the SVG path code won't render properly, for instance:

• M3,.6 – parse to M, 3, .6 (may be fixed with https://github.com/processing/processing4/commit/9ef40ba48c284ae52e7eae759af325486ca85f1e)
• M.6.7 – parse to M, .6, and .7
• …etc

This caused a problem with the variable icons, which was fixed commit 805306fd1b4eeeac35bf1c29693d751edf349f57, so using the previous version of the SVGs should do the trick for testing.

Test code:

static final String[] names = { 
  "array", "boolean", "byte", "char", "double", "float",  
  "integer", "long", "object", "short", "string"
};

void setup() {
  size(250, 550);
  textAlign(LEFT, CENTER);
  textSize(24);
  fill(0);

  int each = 50;
  int pos = 0;
  for (String name : names) {
    PShape s = loadShape(name + ".svg");
    shape(s, 0, pos, each, each);
    text(name, 60, pos + each/2);
    pos += each;
  }
  saveFrame("issue.png");
}

Start at loadShape() and the SVG path parsing entry point, then reproduce the supplied sketch with the previous SVG versions mentioned in the issue. Check tokenization for paths such as M3,.6 and M.6.7; done means leading-decimal coordinates parse correctly and the variable icons render as expected.
