(GD Paint) Brush strokes aren't continuous if you move your mouse faster

[cgormaz]

Which demo project is affected:
GD Paint Demo 4.2 (https://godotengine.org/asset-library/asset/2768)

Issue description:
First of all, this demo is amazing! My only complaint is that if you move your mouse a bit fast, you can see each "circle" instead of a continuous line. While it's not necessary for each circle to be exactly 1px away from each other, it would be great to limit the separation between them a bit, or maybe make it place a new circle more often. I apologize if this is more of a feature request than a bug.

Keep up the amazing work!
