PShape.contains() is broken for transformed shapes (double invert)

contains() in PShape is inverting the matrix twice, so it cancels itself out and hit-testing runs in the wrong space.

In PShape.java:

PMatrix inverseCoords = matrix.get();
inverseCoords.invert();
inverseCoords.invert();
inverseCoords.mult(new PVector(x, y), p);

That second invert() should not be there.

So for translated/rotated/scaled shapes, contains(x, y) gives wrong answers.

Quick repro:

PShape s = createShape(RECT, 0, 0, 50, 50);
s.translate(100, 100);
println(s.contains(120, 120)); // false, should be true

Expected: point-in-shape test respects the shape transform.
Actual: transform handling is wrong because inverse matrix is never actually applied.

PShape.java の contains() から始めます。ここでは、issue が連続する 2 回の行列反転を特定しています。提供された translated-rectangle repro を実行し、余分な反転を削除すると、変換されたシェイプに対して contains(120, 120) が true を返すことを確認してください。
