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");
}

Inizia da loadShape() e dal punto di ingresso del parsing dei percorsi SVG, quindi riproduci lo schizzo fornito con le versioni precedenti di SVG menzionate nell’issue. Controlla la tokenizzazione di percorsi come M3,.6 e M.6.7; il lavoro è completato quando le coordinate con decimale iniziale vengono analizzate correttamente e le icone variabili vengono renderizzate come previsto.
